Abstract

Schwannoma, typically a non-cancerous tumor originating from Schwann cells, seldom occurs in the retroperitoneal area. Its clinical manifestation varies, often remaining asymptomatic for an extended period until it enlarges, exerting pressure on neighboring organs. This article presents a unique instance of retroperitoneal pelvic schwannoma in a 75-year-old woman, initially presenting with unusual lower back discomfort. Imaging was used to characterize the tumor, and anatomopathological examination established the preoperative diagnosis of pelvic schwannoma and its benign nature. The clinical, imaging, and anatomopathological aspects of this pelvic schwannoma case are elucidated herein.

Abstract

Askin's tumor is a rare primitive neuroectodermal tumoral developing from the soft tissues of the chest wall. Its diagnosis approach is complex and requires a multidisciplinary team. We report a case of an incidentally discovered anterior chest wall Askin tumor in a 27-year-old woman, following a forced chest pain, having motivated to perform a chest CT scan. We will discuss the nonspecific imaging findings and the characteristic histopathological features that confirm a diagnosis.

Abstract

Immune check point inhibitor has made far-reaching changes in the management of lung adenocarcinoma improving drastically the prognosis. We present a case of a 50 years old women beneficiary of pembrolizumab who has suffered an acute pneumonitis diagnosed with CT imaging the days following the initiation of the drug. The occurrence of immune-related events such as pneumonitis complicates the use of immunotherapy and requires a well verse radiologist in the matter to diagnosis and helps prevent further aggravation.

Abstract

The peritoneal pseudotumor localization of tuberculosis is a rare clinical form, representing 1 to 3% of extrapulmonary site of tuberculosis. It represents the sixth most common extra pulmonary site of tuberculosis. It is a great mimicker with major overlapping clinical and imaging features. Differentiating peritoneal tuberculosis and peritoneal carcinomatosis in imaging remains challenging. We present a case of a 37-year old woman complaining of chronic abdominal pain and distension who has been diagnosed to have peritoneal carcinomatosis based on CT findings, histopathological study then revealed necrotizing, granulomatous inflammation consistent with tuberculosis. This case showed the interest to be aware of the common and uncommon imaging features of tuberculosis by radiologists to better assess for alternative differential diagnosis.

14. Leptomeningeal Metastasis Mimicking a Subacute Epidural Hematoma: Case Report

Medicine (General), R5-920
Abstract

Leptomeningeal carcinomatosis is extremely rare in colorectal adenocarcinoma, its incidence is far less than 1%. The neurological symptoms are pleomorphic. The most common symptoms included Headache, ataxia, cranial nerve palsies, meningismus, focal weakness or numbness. MRI is the most sensitive and specific imaging method for screening, positive diagnosis and pre-treatment of leptomeningeal carcinomatosis. The presence of appropriate neuroimaging abnormalities in a patient with typical clinical features and history of colorectal adenocarcinoma enables to make the diagnosis of leptomeningeal metastases. As well as a biological confirmation is necessary. Treatment usually comprises site-specific radiation therapy in addition to intrathecal and systemic chemotherapy. The case aims to describe the MRI characteristics of leptomeningeal metastases so as to formulate the diagnosis and the subsequent treatment.

Abstract

Abdominal wall hernias are a common imaging finding. Their most common complications include bowel obstruction, incarceration, strangulation and trauma. We report an exceptional case of spigelian hernia in 55 years old women complicated by perforation and massive subcutaneous emphysema which was correctly diagnosed by CT scan. This case showed the interest of CT scan with multiplanar reconstructions in the confirmation of the diagnosis.

20. Uncommon orbital metastasis in ductal breast carcinoma: a rare presentation 12 years after treatment.

Abstract

Orbital metastasis originating from breast carcinoma, particularly ductal carcinoma, represents a rare clinical entity, with lobular carcinoma usually being more common. Long-term surveillance in breast cancer patients is crucial for early detection of metastasis. Herein, we present a case of a 70-year-old woman with a history of left ductal breast carcinoma, diagnosed and treated 12 years ago. She then developed left eye vision loss, diplopia, enophthalmos, and chemosis in October 2024. Imaging revealed orbital metastasis involving the left superior and lateral rectus extraocular muscles. Biopsy confirmed the diagnosis of orbital metastases arising from ductal breast carcinoma. This case underscores the significance of long-term surveillance in breast cancer patients, as metastasis can manifest years after the initial diagnosis. Despite its rarity, orbital metastasis warrants consideration in the differential diagnosis of ocular symptoms in patients with a history of breast carcinoma. Treatment primarily aims at palliation and preserving visual function, with prognosis typically poor. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: Merkel cell carcinoma (MCC) is an aggressive skin tumor of neuroendocrine origin that derives from Merkel cells and occurs predominantly on the head or neck of elderly individuals at an average age of 69 years old. Its main risk factors are immunosuppression and ultraviolet exposure. The diagnosis is established on the histological aspect and completed by immunohistochemistry. Case Report: We report the case of a 65-year-old female patient, with no particular antecedents, who had right axillary swelling. Thoracic computed tomography (CT) showed a large right axillary mass of irregular contours, lobulated, heterogeneously enhanced after CP injection with central hypodense zone of necrosis. The confrontation of the morphological aspect and the results of the immunohistochemistry carried out made it possible to retain the diagnosis of Merkel cell carcinoma. Conclusion: Merkel cell carcinoma is a very aggressive cancer of the elderly. In case of doubt, a biopsy for histological confirmation should be performed. The therapy is usually based on a radical surgery followed by adjuvant radiotherapy.

Abstract

Atypical breast hyperplasia is a precancerous lesion with a high risk of invasive carcinoma. The atypical character of hyperplasia is confirmed by the absence of anti Ck5/6 immuno-marking in the immunohistochemical study. These lesions are difficult to identify on breast ultrasound. Magnetic reasoning imaging shows non-mass enhancement which can have focal or regional distribution. We report the case of a 53-year-old woman, with a history of infiltrating lobular carcinoma of the right breast treated, in which the senological findings were in favor of atypical ductal hyperplasia of the left breast.
