On the computed tomography image, there was large, well-defined soft tissue mass in the left side of the retroperitoneum, and there was no visible left testis or seminal vesicle. Aft...
Hemangioblastoma is a rare neoplasm occurred in soft tissue. Herein, we present an intriguing case of sporadic hemangioblastoma in the retroperitoneum occurring in a 59-year-old male.
