A Rare Case of Idiopathic Vascular Renal Tumor Renal Hemangioma: A Case Report

Abstract

Renal hemangioma is a rare benign vascular tumor which can present with painful or painless gross hematuria. Its preoperative diagnosis is extremely difficult due to non-specific imaging findings and can also mimic other disease entity.

This is a case of a 31-year-old female who presented with recurrent gross hematuria with no antecedent cause. KUB ultrasound and CT stonogram showed insignificant findings of the cause of hematuria. Renal Angiogram revealed multiple vascular channels with arterial and venous connections at the upper pole of the right kidney with the impression of gross hematuria secondary to AV malformation. Simple Nephrectomy was done to address the hematuria wherein histopathologic findings were indicative of renal hemangioma. Patient did not report any episode of gross hematuria since the operation.
