A Case of Renal Angiomyolipoma Extending into the Renal Cyst Which was Confused with Renal Pelvis Tumor / 대한비뇨기과학회지

ABSTRACT

Renal angiomyolipoma is composed of mature fats, smooth muscles and abnormal blood vessels which arises mainly from renal parenchyme and compresses the calyx or protrudes the renal cortex, but which extends into the renal cyst is rare. Recently it can be easily diagnosed preoperatively by several diagnostic modalities such as ultrasonography, computed tomography and several clinical signs associated with tuberous sclerosis, although it`s clinical and radiological features are similar with renal cell carcinoma. We report a case of renal angiomyolipoma without tuberous sclerosis, extending into the renalcyst, which was confused with renal pelvis tumor in a 73 years old male.
