ABSTRACT

Introduction: Renal angioleiomyoma is a very uncommon benign tumor and, invading the main renal vein, even rarer. Objective: To describe the clinical, imaging and therapeutic characteristics, of a patient diagnosed with renal angioleiomyoma. Case presentation: A 23‐ year‐ old patient with history of health. He attended in the external consultation of Urology for having presented gross haematuria, with light left flank pain. No history of previous trauma or other symptoms of any illness was recorded. The general physical exam was normal and, in the urogenital apparatus, had left varicocele. Studies of blood analysis were all normal, as was the general examination of urine. The abdominal ultrasound detected a 9 cm in diameter tumor, in the middle and lower pole of the left kidney with cysts inside; the right kidney was normal. The thorax‐ abdominal axial computerized tomography confirmed the tumoral lesion, which enhanced with the contrast medium; not other intrabdominal and pleuropulmonary alterations were found. Results: The left total nephrectomy was performed, by the anterior transperitoneal route, without complications. The histopathological diagnosis was renal angioleiomyoma with tumoral thrombus in the main renal vein; this was confirmed by inmunohystochemistry. The evolution of the patient has been satisfactory. Conclusions: The detailed analysis of the three‐ phase axial computerized tomography images, in the study of renal tumors, contributes to establish the differential imaging diagnosis of these, especially in young patients without associated risk factors.
