No abstract available. Article truncated after 150 words. A 72-year-old woman was referred to our practice from an outside hospital with a history of tracheal mass with impending airway compromise. She originally presented with several days of dyspnea, stridor, and an increasingly muffled voice. She also provided a history of severe shortness of breath, but only when eating. Interestingly, she had no trouble swallowing. CXR findings at the outside hospital (Figure 1) prompted a CT (Figure 2A), which further prompted transfer of patient to our facility. The patient had a history of hypertension, hyperlipidemia, type 2 diabetes and obstructive sleep apnea. Her past surgical history included C-section and hysterectomy. The patient was a never-smoker with no significant drinking or drug usage history. The patient had no recent travel or exposure history. Review of symptoms otherwise negative. Although the patient had no formal diagnosis of asthma, she was on Mometasone/formoterol, 2 puffs bid and also had an albuterol rescue …

No abstract available. Article truncated after 150 words. An 85-year-old man presented to our institution for a second opinion and for management of a recurrent left-sided pleural effusion. The patient has a history of CLL, which was diagnosed with a chest wall biopsy 4 years prior to presentation. Since that time, he has undergone chemotherapy and had a good response. In the past 18 months, the patient has had their left-sided pleural effusion drained 24 times. The patient also has a history of hypothyroidism and has had a cholecystectomy. The patient brought multiple outside imaging studies with him for review. An image capture from a recent ultrasound-guided left thoracentesis (Figure 1A) demonstrated, in retrospect, a pedunculated left lower lobe mass. An outside PET-CT (Figure 1B) was also available, confirming the presence of this mass, which had relatively uniform, low level FDG uptake such that it evade notice on first interpretation. A CT angiogram (Figure 2) demonstrated a large …

Further workup revealed a new diagnosis of myelodysplastic syndrome (MDS) and subsequent bronchoalveolar lavage (BAL) and histology results were consistent with secondary PAP, likely due to patient’s underlying hematologic disease. Pulmonary alveolar proteinosis (PAP) is a rare disease characterized by the accumulation of lipoproteinaceous material in the lung alveoli. There are two types of PAP that occur in adults: Idiopathic/ autoimmune and Secondary PAP. Idiopathic/autoimmune PAP is more common and is thought to result from antibody production against granulocyte-macrophage-colony-stimulating factor (GM-CSF) that regulates surfactant homeostasis. Secondary PAP results from a precipitating condition, often inhalation exposure, underlying malignancy, or immunocompromise. The clinical manifestations of PAP are nonspecific and includes dyspnea, nonproductive cough, fatigue, and weight loss. CT may show nonspecific findings of smooth, bilateral interlobular septal thickening superimposed on a background of ground-glass opacification (crazy-paving). Diagnosis is confirmed with …

No abstract available. Article truncated after 150 words. A 71-year-old man presented to our pulmonary clinic with a complaint of worsening dyspnea, which seems to be positional in nature. Symptoms were exacerbated by bending over or laying down too quickly. The patient was known to our practice, having had a kidney transplant 17 years ago, a left upper lobectomy for squamous cell carcinoma 6 years ago (no recurrence), and has been on fluconazole for 4 years due to disseminated coccidioidomycosis (cocci) with cavitary pulmonary involvement. The patient had recurrent DVTs 2 years ago and is on Eliquis. On top of that, the patient had COVID 1 year ago, but had recovered. An outside sleep study was remarkable for overnight hypoxia. Outside pulmonary function testing (PFTs) demonstrated a combined restrictive and obstructive picture. An outside chest CT failed to demonstrate any findings that would suggest COVID-related changes or progression of cocci as a potential cause. A V/Q scan was …

No abstract available. Article truncated after 150 words. A 70-year-old man presented with persistent cough productive of clear sputum which had persisted approximately 12 months after COVID-19 infection. The patient reported a more recent history of night sweats and had also recently developed what he described as “blisters” on his chest wall and right shoulder starting 4 weeks prior to presentation that “opened up” giving off a bloody discharge. The patient had been treated with Bactrim and Doxycycline without improvement and reported a 10-pound weight loss over the past several months. The patient was a never-smoker with no significant travel history and a past medical history of asthma, GERD, gout, and chronic rhinitis. Vital signs and physical exam were normal, except for a 1 cm open wound in the center of the patient’s chest [Figure 2A]. A chest CT performed as part of the patient’s workup demonstrated a spiculated mass in the left upper lobe with adjacent mediastinal …

No abstract available. Article truncated after 150 words. A 62-year-old woman presented to an outside hospital with chronic cough, prompting a CXR. Findings further prompted unenhanced chest CT to evaluate possible pulmonary nodules. The CT demonstrated multiple scattered, solid and centrilobular pulmonary nodules, most of which were small but there were two >1 cm nodules, one in the right upper lobe (RUL) and a second in the lingula (Figure 1A,B). A subsequent FDG PET-CT was performed demonstrating increased metabolic activity in the RUL nodule with no activity in the lingular nodule (Figure 1C,D). Biopsy of the RUL nodule was consistent with a carcinoid. At this point the patient was referred to our center for further management. A repeat chest CT failed to demonstrate any significant change in the nodules. MIP and MinIP reconstructions from that examination demonstrate multiple small, solid pulmonary nodules (arrows) (Figure 2A), many of which were associated with air-trapping resulting in pulmonary mosaicism (circled) (Figure …

No abstract available. Article truncated at 150 words. A 22-year-old man with a known diagnosis of Tuberous Sclerosis Complex (TSC) presents for a follow-up unenhanced chest CT to re-evaluate pulmonary nodules seen in the lung bases on a prior abdominal CT. The patient also has a history of multiple renal lesions consistent with lipid-poor angiomyolipomas based on previous abdominal MRI findings. The chest CT demonstrated multiple scattered, randomly distributed sub-centimeter pulmonary nodules of solid or subsolid morphology [Figure 1A]. Those nodules visible in the lung bases on the prior abdominal CT had remined stable over the 12-month interval consistent with multifocal microscopic pneumocyte hyperplasia (MMPH)[Figure 1B,C]. Myocardial fatty foci (MFF) were visualized in the heart on soft tissue window display settings [Figure 2A] as were multiple scattered sclerotic bone lesions on bone window display settings [Figure 2B,C]. No pulmonary cysts were seen to suggest lymphangioleiomyomatosis (LAM) and there were no thoracic lymphangiomas. MMPH represents a benign hamartomatous proliferation …
