3 CASES OF RENAL ANGIOMYOLIPOMA

We report three non-typical cases of renal angiomyolipoma including cl inical features, imaging examinations (with ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI) and angiography) and histological findings, Microaneurysms observed by angiography were co mmon to the three cases and were considered to be an important finding in the diagnosis of renal angiomyolipoma, Moreover, the short tau inv ersion recovery (STIR) method of MRI, which suppresses photon signals of fat, was considered to be useful for the diagnosis. Case 1 was acco mpanied by spontaneous rupture, Case 2 was difficult to diagnose becau se of little fat tissue and Case 3 revealed a very small tumor.
