A rare case of a sporadic retroperitoneal hemangioblastoma

Hemangioblastoma is a rare, benign, and morphologically distinctive tumor. In most cases, the tumor involves the central nervous system. Extraneural occurrences are rare, with just a few reports of hemangioblastoma situated outside of neural tissue, such as the retroperitoneum. We report a case of s...

Sumario:Hemangioblastoma is a rare, benign, and morphologically distinctive tumor. In most cases, the tumor involves the central nervous system. Extraneural occurrences are rare, with just a few reports of hemangioblastoma situated outside of neural tissue, such as the retroperitoneum. We report a case of sporadic retroperitoneal hemangioblastoma in an 87-year-old male patient, diagnosed as an incidental finding in a CT scan performed because of kidney stone disease. The CT scan showed a mass in the retroperitoneum posterior to the inferior vena cava. The patient reported no remarkable symptoms. We describe our path to diagnosis, the possible differential diagnosis for retroperitoneal masses, and the histopathologic features of the tumor. There are <250 reported extra neuraxial hemangioblastomas and just 14 reported cases situated outside of the neural tissue. Our case is the eighth case report of a hemangioblastoma arising from the soft tissue of the retroperitoneum.
