CT and MR imaging of a huge retroperitoneal synovial sarcoma: A case report.

Retroperitoneal synovial sarcoma is extremely rare, with only a few cases reported in the literature. The diagnosis is often made late, due to anatomical considerations, with common symptoms including low back pain and weight loss. Imaging is critical for diagnosis, often revealing a heterogenous mass with the "triple sign" and calcifications.

Zinner syndrome: A rare congenital cause of infertility.

Zinner syndrome is a rare congenital malformation characterized by cystic seminal vesicles and ejaculatory duct obstruction in association with ipsilateral renal agenesis. It appears to be frequently linked to infertility. However, recent advances in imaging, notably MRI, have led to an increase in the diagnosis of this pathology.

Isolated proximal tibiofibular dislocation: Don't miss it.

Proximal tibiofibular joint (PTFJ) dislocation is a rare but significant traumatic knee injury that often goes undetected due to its subtle presentation and the rarity of the condition. It accounts for less than 1% of all knee injuries, making it an uncommon diagnosis in clinical practice. Despite its rarity, the implications of missing this injury can be profound, leading to chronic pain, instability, and potential nerve damage if not appropriately managed.

Progressive ataxia and palatal tremor (PAPT) with hypertrophic olivary degeneration (HOD): A case report.

Palatal tremor has been subdivided into essential (EPT) and symptomatic palatal tremor (SPT). Progressive ataxia and palatal tremor syndrome (PAPT) is a subgroup of symptomatic palatal tremor (SPT). It can be divided into familial and sporadic forms.

Lemmel syndrome: an unusual cause of biliary obstruction secondary to a duodenal juxta-ampullary diverticulum: a report of two cases.

abdominal pain or jaundice. Cross-sectional imaging is beneficial in making the diagnosis noninvasively, thus eliminating other pathologies of the peri-ampullary region. We present 2 cases of Lemmel's syndrome whose diagnosis is retained based on a CT scan and magnetic resonance cholangiopancreatography.

Primary amenorrhea secondary to imperforate hymen.

Hymen imperforation is uncommon. Symptoms include primary amenorrhea, cyclical lower abdominal pain, and rarely a pelvic mass syndrome. Delayed discovery may lead to endometriosis and infertility.

Cerebellar hemangioblastoma: Case report with review of the literature.

Originally recognized by Cushing and Bailey, hemangioblastoma is a developmental vascular neoplasm that is predominantly found in the posterior fossa. It is a highly vascularized tumor, with well-differentiated histologic features. Although rare, it remains the most common primary tumor of cerebellum in adults, along with metastases.

Cystic meningioma: A case report with a literature review.

Cystic meningiomas are very rare tumors of the central nervous system. We report the case of a 62-year-old female how presented headaches resistant to usual analgesics with behavior disorders. Cerebral CT scan showed a right frontal extra-axial tumor with firm and cystic component, brain MRI evoked the diagnosis, surgery removed the entire tumor and histological examination confirmed it.

Tuberculous common bile duct stricture mimicking a cholangiocarcinoma: A case report.

Biliary involvement during abdominal tuberculosis is extremely uncommon and represents a challenging diagnosis that can easily be mistaken for a malignant etiology. We report the case of a 40 years old male who presented with anorexia, chronic abdominal pain, and progressive obstructive jaundice. Abdominal computed tomography demonstrated distal narrowing with wall thickening of the main biliary duct, along with enlarged lymph nodes and signs of portal hypertension.

[Rare digestive tumors: gastrointestinal stromal tumors (GISTs): about a case of small bowel location and literature review].

Gastrointestinal stromal tumors (GISTs) are a rare group of mesenchymal tumors mainly occurring in the gastrointestinal tract. Previously, GISTs were classified as smooth muscle tumors also known as leiomyomas, leiomyosarcomas or leiomyoblastomas. However, since the advent of immunohistochemistry, GISTs have been diagnosed on the basis of the identification of c-kit-positive cells.

[Mirizzi's syndrome: a rare cause of biliary tract obstruction: about a case and review of the literature].

Mirizzi's syndrome is a rare complication of chronic vesicular lithiasis with prevalence ranging from 0.7% to 1.4% among patients who have undergone cholecystectomy.

[Giant congenital intrapericardial left atrial appendage aneurysm: about a case and review of the literature].

Left atrial appendage aneurysm is a very rare heart anomaly. It may be congenital or acquired, secondary to inflammatory or degenerative processes. Most cases are asymptomatic.

Dual intersection syndrome of the forearm: a case report.

The intersection syndrome, described since the 19(th) century, is an uncommon disorder associated with rubbing at the crossing point between the first dorsal compartment muscles and the radial wrist extensor muscles. Imaging modalities used to diagnosis this syndrome includes ultrasonography and magnetic resonance imaging. We reported a case of a 60-year-old man presented to our formation with painful swelling on the dorsum of the wrist and forearm.
