Abstract
Angiomyolipoma (AML) is a benign renal neoplasm. Preoperative diagnosis is important because of the different surgical approaches to benign and malignant tumors. Angiographic findings of AML and renal carcinoma may be similar and differentiation difficult. Bβmode ultrasound examination of AML demonstrates a different image pattern which may be helpful in differentiation.

The ultrasound findings in renal transplant rupture have been infrequently reported in the literature. It has been reported as an echogenic mass above the superior pole of the kidney without intrinsic renal abnormality. We wish to report a case showing both intrarenal and extrarenal hematoma. In the
## BACKGROUND. Angiomyolipoma is a benign kidney tumor with distinctive pathologic and clinical features. Because the prognosis differs from many other renal and retroperitoneal tumors, accurate diagnosis on cytologic material may be important for appropriate management.
