Subepithelial hematoma of the renal pelvis (Antopol-Goldman lesion): a case report

Abstract

Abstract

Antopol-Goldman lesion or subepithelial pelvic hematoma of the kidney is a benign lesion and a rare cause of hematuria. Its clinical and radiologic manifestations resemble upper urinary tract neoplasms. A 36-year old woman presented with complaints of macroscopic hematuria and left-sided lumbar pain. A computed tomography scan showed a filling defect of the left renal pelvis. Cystoscopic findings of the bladder were normal. Retrograde pyelography confirmed the presence of the filling defect. Examination of the renal pelvis with flexible ureterorenoscopy failed because of ureteral kinking. A left ureteronephrectomy was performed due to the persistence of hematuria. Histopathologic diagnosis was made as subepithelial hematoma (Antopol-Goldman lesion).
