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.

Clinical report of metacarpal melorheostosis: a rare disease with "the dripping candle wax" appearance on different imaging modalities.

Melorheostosis is a rare benign bone dysplasia characterized by dysostosis and sclerosis. The classic "dripping candle wax" appearance on imaging is a typical finding for the diagnosis. The authors report the case of a patient presenting with a hard and painful mass on the dorsal side of the hand.

Transposition of the inferior vena cava with hemiazygos continuation: A rare case report.

Hemiazygos continuation of a left-sided inferior vena cava (IVC) is an extremely rare developmental anomaly. We present the case of a male patient in whom this condition was incidentally discovered during a thoraco-abdominopelvic CT scan. With the widespread use of contrast-enhanced computed tomography and magnetic resonance angiography, the detection of congenital IVC anomalies has become more accessible.

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.
