title: Symptomatic solitary right renal vein aneurysm: a case report.
abstract: Renal vein aneurysms are very uncommon. Those located in the right side are exceptional. A symptomatic, solitary, voluminous aneurysm of the right renal vein in a 33-year-old man is reported. The lesion was diagnosed preoperatively as a renal tumor. The pathologic study of the nephrectomy specimen disclosed a thrombosed saccular aneurysm measuring 5.5 cm with marked medial atrophy of its wall. Recognition that a mass like this reported is of vascular origin is very important to avoid percutaneous biopsy which could be potentially hazardous; and for undertaking conservative prophylactic surgery. Renal venography is indicated for the diagnosis of these lesions.
