Cystic adrenal mass revealing a pheochromocytoma in the setting of multiple endocrine neoplasia: A case report.

Pheochromocytoma, a neuroendocrine tumor, represents a rare medical condition characterized by the excessive secretion of catecholamines. These tumors often exhibit distinctive features on imaging studies, notably appearing hypervascular. Furthermore, they may present as cystic masses with thin walls, a characteristic that becomes more evident following the administration of contrast medium. The cystic form of adrenal pheochromocytoma, as exemplified in our case, is particularly uncommon, thus underscoring the importance of recognizing its atypical presentation. Accurate diagnosis hinges on a thorough understanding of both the clinical manifestations and radiological findings suggestive of pheochromocytoma. However, definitive confirmation typically necessitates histological examination of the surgical specimen post-adrenalectomy. By shedding light on this rare variant, our case emphasizes the critical role of comprehensive diagnostic approaches in managing such complex medical conditions. Additionally, it underscores the significance of multidisciplinary collaboration among clinicians, radiologists, and pathologists to ensure timely and accurate diagnosis, ultimately guiding appropriate treatment strategies and optimizing patient outcomes.

Acute toxic hippocampal encephalopathy in heavy cannabis users: A case report.

Cannabis use is increasing rapidly among young people worldwide despite the deleterious effects of this toxic substance on health. We report a case of acute hippocampal encephalopathy in a heavy cannabis user (8-10 joints/d for 6 years) who presented with a nonfebrile status epilepticus. Brain magnetic resonance imaging revealed bilateral and symmetrical high-signal abnormalities in the hippocampal regions. The damage to these regions is often severe, long-lasting, and sometimes irreversible. Therefore, every doctor (emergency doctor, resuscitator, neurologist...) is asked to request a brain MRI in case of neurological signs in a young cannabis user.

Breast adenomyoepithelioma diagnosed on core needle biopsy: a diagnostic challenge.

Adenomyoepithelioma represents a rare tumor of the breast characterized by biphasic proliferation of epithelial and myoepithelial cells. Owing to its nonspecific clinical presentation, the rarity, and the morphological pitfalls in differential diagnosis, the diagnosis may be extremely difficult especially on limited samples such as core needle biopsy; thus, the diagnosis is histological, which is confirmed by the specificities of the immunohistochemical analyses. Here we report a case of a 64-year-old female who presented a benign adenomyoepithelioma diagnosed on core needle biopsy, review the clinicopathological features of breast adenomyoepithelioma diagnosed on core needle biopsy, and discuss the useful clues to prompt accurate diagnosis.

Retroperitoneal lymphatic malformations: A case report.

Retroperitoneal lymphatic malformation is a rare benign vascular malformation, of various locations, which can reveal itself at any age in its abdominal localizations. The retroperitoneal localization of this malformation is extremely rare. The clinical symptomatology is polymorphic depending on the lesion volume and the presence or absence of complications. The diagnosis is evoked by the liquid character of the retroperitoneal mass on ultrasound, CT scan and abdomino-pelvic MRI, brought during surgery and confirmed by the histological study of the surgical specimen. The treatment of choice is complete surgical removal of the mass.

Primary umbilical endometriosis revealed by tender and hemorrhagic umbilical swelling during menstruation.

Endometriosis is a relatively uncommon benign pathology that accounts for 0.5%-1% of all extra-pelvic endometriosis. This pathology is characterized by the presence of ectopic endometrial tissue outside the endometrial cavity and is accompanied by the clinical appearance of a bleeding umbilical nodule. Despite the non-specificity of the characteristic imaging signs, abdominal ultrasound and magnetic resonance imaging aid in diagnosis. We describe a case of primary umbilical endometriosis, as well as the clinical aspects and role of imaging in the positive diagnosis of this uncommon pathology.
