Primary leiomyosarcoma of the abdominal aorta is a rare but fatal cause of renovascular hypertension that can mimic Takayasu's arteritis or retroperitoneal hematoma.
Warrants consideration in atypical renovascular hypertension differentials; leaves open optimal diagnostic and therapeutic strategies for this rare entity.
We describe the case of a 44-year-old woman who presented with renovascular hypertension caused by primary leiomyosarcoma of the abdominal aorta that had metastasized into the renal arteries. Despite an extensive radiological evaluation, the diagnosis was mistaken first for Takayasu's arteritis and then for retroperitoneal hematoma or neoplasm. The patient developed renal failure due to bilateral renal infarction, and died 3 months after her initial presentation with ischemic colitis. Postmortem examination confirmed the diagnosis.

Iguchi et al. (2007) conducted a case report in Renovascular hypertension secondary to leiomyosarcoma of the abdominal aorta (n=1). Primary leiomyosarcoma of the abdominal aorta was evaluated on Clinical outcome. Primary leiomyosarcoma of the abdominal aorta is a rare but fatal cause of renovascular hypertension that can present with tumor embolization into the renal arteries and rapid clinical deterioration.
