Renal Schwannoma: A Rare Pathology
Article Sidebar
Main Article Content
Abstract
Schwannomas are benign neoplasms that originate from Schwann cells of the peripheral nerves heath. They are most commonly found in the head, neck, and extremities, although up to 3% occur in the retroperitoneum, with renal involvement being exceptional. The renal hilum is the most frequent site of origin; however, many renal schwannomas are located in the parenchyma, mimicking renal cell carcinoma, or in the perirenal space, broadening the range of diagnostic possibilities. We present a case in which a mass in the right anterior perirenal space was identified on imaging and confirmed by percutaneous biopsy.
