Imaging of Subepithelial Hematoma of Renal Pelvis (Antopol-Goldman Lesion) Simulating Tumor: A Case Report

ABSTRACT

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