Abstract

Traumatic diaphragmatic rupture remains a diagnostic challenge for both radiologists and surgeons. In recent years, multidetector CT has markedly improved the diagnosis of diaphragmatic injury in polytrauma patients. Herein, we describe two cases of subacute presentation of traumatic diaphragmatic rupture from a penetrating rib fracture and subsequent intrathoracic herniation of omental fat, representing the CT “funky fat” sign.

Abstract

A 29-year-old non-smoking female with a history of recurrent AML presented with worsening dyspnea. A CT scan revealed an 8 X 7 mm polypoid soft tissue nodule 8 mm distal to the carina in the left mainstem bronchus. She was brought to the operating room and a nearly obstructing soft fleshy tumor in the left mainstem bronchus just distal to the carina was removed with bronchoscopy. Pathology revealed a low grade mucoepidermoid carcinoma 0.8 cm in largest dimension with negative margins. The patient returned for a resection and was intubated with a right mainstem double lumen tube and placed in left lateral decubitus. After posterolateral thoracotomy, the azygos vein was divided to mobilize the esophagus and retract it laterally. Level 4 and 7 lymph node dissection were performed to obtain access to the anterior tracheal and subcarinal spaces. There was minimal dissection lateral to the trachea to minimize risk of ischemia. One centimeter of trachea just proximal to the carina was circumferentially isolated with umbilical tape for retraction. We bronchoscopically confirmed the location for transection and advanced a jet ventilator catheter distally. We resected one centimeter of left mainstem bronchus. We inspected the lumen of the airway to confirm no gross residual disease and confirmed negative pathologic margin before performing an end-to-end anastomosis with interrupted absorbable sutures under both jet and cross-table ventilation. Postoperatively, the patient had an uncomplicated course and was discharged without any supplemental oxygen on postoperative day 6. Final pathology was low grade mucoepidermoid carcinoma, T1aN0.

Abstract

Distinction between multiple primary cancers and intrapulmonary metastases in patients with synchronous multifocal lung cancer can be challenging. Histological and genotypic assessment of multifocal lung tumors have been suggested to influence the staging. The aim of this study was to determine the role of morphology and genotype in staging of surgically treated multifocal non-small cell lung carcinoma. Synchronous lung cancers from 60 patients (42 with adenocarcinoma and 18 with squamous cell carcinoma), clinically considered to represent intrapulmonary metastases, were histologically subtyped according to the 2015 World Health Organization classification of lung tumors and subjected to genotypic analysis (KRAS, EGFR, BRAF, PIK3CA, ALK, MET and ROS1 in adenocarcinoma and PIK3CA and p16 in squamous cell carcinoma). Concordance between clinical criteria and histological subtyping was identified in about 50% of cases (P0.0001). Genotypically, 44% of adenocarcinomas and 60% of squamous cell carcinomas with identified molecular alterations were considered to be intrapulmonary metastases. Concordance between histological and molecular staging was observed in 89% of adenocarcinomas and 56% of squamous cell carcinomas. Univariate survival analyses failed to demonstrate significant differences in overall or cancer-specific survival in patients with adenocarcinoma and squamous cell carcinomas restaged according to histology and/or molecular profile. Lymph node metastases (N1/N2 vs N0) (P=0.03) and age65 years (P=0.05) were associated with shorter overall survival. In addition, squamous cell carcinomas with p16 deletion showed shorter overall survival when compared with squamous cell carcinomas without p16 deletion (P=0.05). No correlation between other molecular alterations, clinico-pathological characteristics and prognosis was found. Our study demonstrates that a comprehensive genotypic and morphological assessment of surgically treated multifocal lung cancers is feasible but not sufficient to establish their clonal relationship and prognosis.

Abstract

Roughly 30% of carcinoids are found in the thoracic cavity, with the overwhelming majority of these being found in the lung parenchyma. We present a case of a rarely found primary pleural carcinoid incidentally diagnosed in a 73 year old male who presented with recalcitrant spontaneous pneumothorax requiring surgical intervention. The patient was taken to the operating room for a right video assisted thoracic surgery, partial pleurectomy, and talc pleurodesis. At the time of the operation, there were no abnormalities noted in the pleura or chest wall, and the patient did well post operatively. Pathologic examination of the pleura revealed a 3mm well differentiated neuroendocrine carcinoid tumor. Laboratory and imaging studies did not indicate another site of tumor. The importance of a multidisciplinary approach to the diagnosis, treatment, and surveillance is emphasized.

Abstract

The National Lung Screening Trial (NLST) is a randomized multicenter study comparing low-dose helical computed tomography (CT) with chest radiography in the screening of older current and former heavy smokers for early detection of lung cancer, which is the leading cause of cancer-related death in the United States. Five-year survival rates approach 70% with surgical resection of stage IA disease; however, more than 75% of individuals have incurable locally advanced or metastatic disease, the latter having a 5-year survival of less than 5%. It is plausible that treatment should be more effective and the likelihood of death decreased if asymptomatic lung cancer is detected through screening early enough in its preclinical phase. For these reasons, there is intense interest and intuitive appeal in lung cancer screening with low-dose CT. The use of survival as the determinant of screening effectiveness is, however, confounded by the well-described biases of lead time, length, and overdiagnosis. Despite previous attempts, no test has been shown to reduce lung cancer mortality, an endpoint that circumvents screening biases and provides a definitive measure of benefit when assessed in a randomized controlled trial that enables comparison of mortality rates between screened individuals and a control group that does not undergo the screening intervention of interest. The NLST is such a trial. The rationale for and design of the NLST are presented.

Abstract

This study investigated the relative efficiencies of a stereographic display and two monoscopic display schemes for detecting lung nodules in chest computed tomography (CT). The ultimate goal was to determine whether stereoscopic display provides advantages for visualization and interpretation of three-dimensional (3D) medical image datasets. A retrospective study that compared lung nodule detection performances achieved using three different schemes for displaying 3D CT data was conducted. The display modes included slice-by-slice, orthogonal maximum intensity projection (MIP), and stereoscopic display. One hundred lung-cancer screening CT examinations containing 647 nodules were interpreted by eight radiologists, in each of the display modes. Reading times and displayed slab thickness versus time were recorded, as well as the probability, location, and size for each detected nodule. Nodule detection performance was analyzed using the receiver operating characteristic method. The stereo display mode provided higher detection performance with a shorter interpretation time, as compared to the other display modes tested in the study, although the difference was not statistically significant. The analysis also showed that there was no difference in the patterns of displayed slab thickness versus time between the stereo and MIP display modes. Most radiologists preferred reading the 3D data at a slab thickness that corresponded to five CT slices. Our results indicate that stereo display has the potential to improve radiologists' performance for detecting lung nodules in CT datasets. The experience gained in conducting the study also strongly suggests that further benefits can be achieved through providing readers with additional functionality.

Abstract

Diagnosis of a bronchopleural fistula (BPF) can be challenging in patients after pneumonectomy and Clagett window. Herein, we present a case of pneumonectomy for advanced lung cancer complicated by a BPF. Herniation of packing material from the open-chest cavity into the fistula and airways on computed tomography was an important clue to making the diagnosis.

Abstract

Background CT scan measures of emphysema and airway disease have been correlated with lung function in cohorts of subjects with a range of COPD severity. The contribution of CT scan-assessed airway disease to objective measures of lung function and respiratory symptoms such as dyspnea in severe emphysema is less clear. Methods Using data from 338 subjects in the National Emphysema Treatment Trial (NETT) Genetics Ancillary Study, densitometric measures of emphysema using a threshold of −950 Hounsfield units (%LAA-950) and airway wall phenotypes of the wall thickness (WT) and the square root of wall area (SRWA) of a 10-mm luminal perimeter airway were calculated for each subject. Linear regression analysis was performed for outcome variables FEV 1 and percent predicted value of FEV 1 with CT scan measures of emphysema and airway disease. Results In univariate analysis, there were significant negative correlations between %LAA-950 and both the WT ( r = −0.28, p = 0.0001) and SRWA ( r = −0.19, p = 0.0008). Airway wall thickness was weakly but significantly correlated with postbronchodilator FEV 1 % predicted (R = −0.12, p = 0.02). Multivariate analysis showed significant associations between either WT or SRWA (β = −5.2, p = 0.009; β = −2.6, p = 0.008, respectively) and %LAA-950 (β = −10.6, p = 0.03) with the postbronchodilator FEV 1 % predicted. Male subjects exhibited significantly thicker airway wall phenotypes (p = 0.007 for WT and p = 0.0006 for SRWA). Conclusions Airway disease and emphysema detected by CT scanning are inversely related in patients with severe COPD. Airway wall phenotypes were influenced by gender and associated with lung function in subjects with severe emphysema.

Abstract

Amyloidosis is a rare diverse condition caused by the pathologic extracellular deposition of abnormal insoluble proteins throughout the body. It may exist as a primary disease or, more commonly, may be secondary to a wide variety of pathologic processes ranging from chronic infection or inflammation to malignancy. Hereditary forms also exist. On the basis of the structure of the protein deposits, more than two dozen subtypes of amyloidosis have been described. A single organ or multiple organ systems may be affected. The radiologic manifestations of amyloidosis are varied and often nonspecific, making amyloidosis a diagnostic challenge for the radiologist. In the chest, the lungs, mediastinum, pleura, and heart may be involved. Lung involvement may manifest as diffuse reticulonodular interstitial thickening, consolidations, or solitary or multiple parenchymal nodules that may calcify, cavitate, and slowly enlarge. Pleural involvement most commonly manifests as pleural effusions. Tracheobronchial involvement may exhibit concentric airway thickening, mural and intraluminal nodules, submucosal calcification, and airway obstruction. Mediastinal and hilar lymph nodes may enlarge and frequently calcify. At cardiac magnetic resonance (MR) imaging, the left ventricular wall is typically thickened, with associated diastolic dysfunction. Delayed contrast material-enhanced cardiac MR imaging typically shows global transmural or subendocardial enhancement. The pathophysiology, classification, treatment, and prognosis of amyloidosis are reviewed, followed by case examples of the appearance of thoracic and cardiac amyloidosis on chest radiographs, computed tomographic (CT) images, and cardiac MR images.

Abstract

The purpose of this study was to characterize the radiologic manifestations of pulmonary mucormycosis with clinical and pathologic correlation.Clinical records, pathology reports, chest radiographs, and CT scans of 32 cases of pathologically proven pulmonary mucormycosis were retrospectively reviewed.The study group included 20 males and 12 females with a mean age of 47 years old. Clinical data were available for 29 patients. Signs and symptoms included fever (n = 23), cough (n = 21), bloody sputum (n = 9), dyspnea (n = 7), and chest pain (n = 6). Four patients were asymptomatic. Most patients were either immunocompromised (n = 20) or had diabetes mellitus (n = 9). Sputum or bronchoalveolar lavage cultures showed no growth in 17 of 18 cases. Diagnoses were confirmed at surgery or autopsy in all cases. Abnormalities seen on chest radiographs included lobar (n = 15) or multilobar (n = 6) consolidation, solitary (n = 7) or multiple (n = 1) masses, and solitary (n = 3) or multiple (n = 2) nodules. Cavitation was seen on chest radiographs in 13 patients, and intracavitary masses were seen in four. Associated radiographic findings included hilar (n = 3) or mediastinal (n = 3) adenopathy and unilateral (n = 6) or bilateral (n = 3) pleural effusion. CT in 19 patients revealed these significant additional findings: splenic (n = 1) or renal (n = 1) involvement, bronchial occlusion (n = 1), extrapulmonary invasion (n = 1), and pulmonary artery pseudoaneurysm (n = 1).In our study, pulmonary mucormycosis typically was manifested in immunocompromised or diabetic patients by consolidation on chest radiographs; cavitation was seen in 40% of patients. CT revealed significant unsuspected abnormalities in 26% of patients. Definitive diagnosis required pathologic demonstration of the organism in affected tissue because cultures from our patients rarely showed growth.

Abstract

Rationale: Severe asthma represents 5‐10% of all asthma, yet remains problematic and poorly understood. Although it is increasingly recognized as consisting of numerous heterogenous phenotypes, their immunopathology, particularly in the distal airways and interstitium, remains poorly described. Objectives:Toidentifythepathobiologyofatypical difficultasthma. Methods: We report 10 from a total of 19 patients (17 women and 2 men)meetingasthmaandsevereasthmadefinitions,requiringdaily systemic corticosteroid (CS) use, with inconsistent abnormalities on chest computed tomography scans, who underwent video-assisted thoracoscopic biopsies for further diagnosis and management. MeasurementsandMainResults:Thepathologyof10ofthe19cases revealedsmallairwaychangesconsistentwithasthma(eosinophilia, gobletcell hyperplasia), but withthe unexpectedfinding of interstitial nonnecrotizing granulomas. These patients had no evidence for hypersensitivity pneumonitis, but 70% of cases had a personal or familyhistoryofautoimmune-likedisease.The10casesweretreated with azathioprine, mycophenolic acid, methotrexate, or infliximab. Nine of 10 showed decreased CS requirements and improved or maintained FEV1 despite lower CS doses. Of the remaining nine patients, six manifested asthmatic small airway disease, alone or in combination with alveolar septal mononuclear cells, but no granulomas, whereas three manifested other pathologic findings (aspiration, pneumonia, or thromboemboli). Conclusions: These data suggest that a subset of severe “asthma” manifests a granulomatous pathology, which we term “asthmatic granulomatosis.” Although identification of this disease currently requires a thorascopic biopsy, alternative approaches to therapy lead to improvement in outcomes.

Abstract

The purpose of this study was to describe the effect of implementing an imaging quality assurance program on CT image quality in the Lung Screening Study component of the National Lung Screening Trial.The National Lung Screening Trial is a multicenter study in which 53,457 subjects at increased risk of lung cancer were randomized to undergo three annual chest CT or radiographic screenings for lung cancer to determine the relative effect of use of the two screening tests on lung cancer mortality. Of the 26,724 subjects randomized to the CT screening arm of the National Lung Screening Trial, the Lung Screening Study randomized 17,309 through 10 screening centers. The others were randomized through the American College of Radiology Imaging Network. Quality assurance procedures were implemented that included centralized review of a random sample of 1,504 Lung Screening Study CT examinations. Quality defect rates were tabulated.Quality defect rates ranged from 0% (section reconstruction interval) to 7.1% (reconstructed field of view), and most errors were sporadic. However, a recurrently high effective tube current-time product setting at one center, excessive streak artifact at one center, and excessive section thickness at one center were detected and corrected through the quality assurance process. Field-of-view and scan length errors were less frequent over the second half of the screening period (p0.01 for both parameters, two-tailed, paired Student's t test). Error rates varied among the screening centers and reviewers for most parameters evaluated.Our experience suggested that centralized monitoring of image quality is helpful for reducing quality defects in multicenter trials.

Abstract

The goal of this study was to assess whether radiologists’ search paths for lung nodule detection in chest computed tomography (CT) between different rendering and display schemes have reliable properties that can be exploited as an indicator of ergonomic efficiency for the purpose of comparing different display paradigms. Eight radiologists retrospectively viewed 30 lung cancer screening CT exams, containing a total of 91 nodules, in each of three display modes [i.e., slice-by-slice, orthogonal maximum intensity projection (MIP) and stereoscopic] for the purpose of detecting and classifying lung nodules. Radiologists’ search patterns in the axial direction were recorded and analyzed along with the location, size, and shape for each detected feature, and the likelihood that the feature is an actual nodule. Nodule detection performance was analyzed by employing free-response receiver operating characteristic methods. Search paths were clearly different between slice-by-slice displays and volumetric displays but, aside from training and novelty effects, not between MIP and stereographic displays. Novelty and training effects were associated with the stereographic display mode, as evidenced by differences between the beginning and end of the study. The stereo display provided higher detection and classification performance with less interpretation time compared to other display modes tested in the study; however, the differences were not statistically significant. Our preliminary results indicate a potential role for the use of radiologists’ search paths in evaluating the relative ergonomic efficiencies of different display paradigms, but systematic training and practice is necessary to eliminate training curve and novelty effects before search strategies can be meaningfully compared.

Abstract

Interstitial lung disease and pulmonary hypertension (PH) are the most common cardiopulmonary findings in patients with systemic sclerosis (SSc). About two thirds of patients suffering from SSc develop scleroderma interstitial lung disease. PH is present in about 20% of SSc patients and is typically associated with severe lung disease, although it may be an isolated manifestation of SSc. High-resolution CT scanning is a key method for evaluating chest involvement. There are four roles of imaging in scleroderma interstitial lung disease: 1) detection of lung involvement, 2) identification of patients likely to respond to treatment, 3) assessment of treatment efficacy, and 4) exclusion of other significant diseases to include PH and cardiac and esophageal abnormalities.
