A Case of Renovascular Hypertension Complicated with Ulcerative Colitis in a 40-year-old male

Abstract

Renovascular hypertension (RVH) is caused from various diseases. Here, we report a case of RVH complicated with ulcerative colitis in a 40-year-old male. The contrast enhanced CT scan and angiography revealed right renal artery occlusion and developed collateral arteries. It also revealed the stenosis of left renal segmental artery and hepatic artery, obstruction of the beginning of both internal iliac arteries, and partial constriction of the abdominal aorta. FDG-PET demonstrated no uptake of FDG in large vessels. Skin and colon biopsies showed no evidence of any vasculitis. Thus, this case was very difficult to diagnose what caused RVH.
