Abstract

Hemangioma in the urinary tract is a very rare benign tumor that usually causes painless or painful gross hematuria. Its preoperative diagnosis is extremely difficult or even impossible. A female 47-year old patient presented with painless gross hematuria that she'd experience for 4 days. The patient underwent abdominal ultrasound, intravenous pyelography (IVP), cystoscopy, urine cytology, retrograde pyelography (RGP), kidney dynamic computed tomography (CT) and surgical excision. She was finally diagnosed with cavernous hemangioma in the renal pelvis.

  • Fig. 1 Intravenous pyelography (IVP) shows a filling defect in the upper calyx of the left kidney.

  • Fig. 2 Retrograde pyelography (RGP) shows a filling defect in the upper calyx of the left kidney.

  • Fig. 3 Kidney dynamic computed tomography (CT) shows a poorly enhancing mass-like lesion in the upper calyx of the left kidney.

  • Fig. 4 Microscopic finding of hemangioma in the renal pelvis. Cavernous hemangioma: lower magnification reveals a typical sinusoidal appearance. Cavernous hemangioma: part of a markedly dilated vascular channel, which is intermixed with red blood cells.
