We report a rare case of subepithelial hematoma of the renal pelvis (Antopol-Goldman Lesion). A 55-year-oldwomen visited our hospital because of gross hematuria. Ultrasonogram showed a 4 cm well-defined solid mass of theleft renal pelvis. Intravenous pyelography revealed compression of the left upper pelvicocalyceal system by themass with contrast filling within the mass. CT scan revealed lobulated contour well defined mass in the left renalpelvis extending into renal parenchyme. A transitional cell carcinoma or renal cell carcinoma was suspectedradiologically, and the patient underwent left total nephrectomy. In Pathology, the lesion turned out to be asubepithelial hematoma. In the differential diagnosis of renal malignancy, a subepithelial hematoma of the renalpelvis may be included.
