M. Ohkawa et al., RENAL ANGIOMYOLIPOMA COMPOSED PRIMARILY OF SMOOTH-MUSCLE ELEMENT - DIAGNOSTIC CONSIDERATIONS, Urologia internationalis, 54(4), 1995, pp. 230-233
A case of renal angiomyolipoma composed primarily of smooth muscle ele
ment is presented. It was a solitary small tumor without evidence of t
uberous sclerosis. The imaging findings including ultrasonography, com
puterized tomography, magnetic resonance imaging, and angiography were
not characteristic of angiomyolipoma, but suggestive of atypical rena
l cell carcinoma, and a simple nephrectomy was performed, The diagnost
ic considerations, particularly imaging features of angiomyolipoma, ar
e discussed.
