Gross Hematuria in Infancy: A Case of Renal Hemangioma Managed Endoscopically.

A case of renal hemangioma in a male infant managed endoscopically is reported. The patient initially presented at 6 months of age to a nephrology clinic with gross hematuria and was found to have what was thought to be a renal cyst. He was referred to urology clinic at 18 months after having continued gross hematuria and negative nephrology evaluation. A magnetic resonance imaging suggested an enhancing mass in the renal pelvis and hydronephrotic upper pole cyst that was mistaken as cyst on ultrasound. A 1.5 × 2.5 cm pedunculated mass in the renal pelvis was resected endoscopically and pathology was consistent with renal hemangioma. He has remained free of hematuria or sign of recurrence on magnetic resonance imaging or renal ultrasound for 9 months.
