Bleeding angiomyolipoma mimiking a ruptured adrenal tumour

R B Nerli et al. Urol Case Rep. .

Abstract

Angiomyolipoma is a benign neoplasm of the kidney, and is the most common renal tumour associated with haemorrhage. Risk of bleeding increases with the size of the angiomyolipoma. We report a case of spontaneous bleeding from an upper polar renal angiomyolipoma mimicking a spontaneous adrenal bleed from a pheochromocytoma.

Keywords: Angiomyolipoma; Embolization; Haemorrhage; Kidney; Nephrectomy.
