Schwannomas rarely occur as neurogenic tumors develop due to nerve Schwann cells. A thirty-five-year-old female reported to our department complaining of Urinary Tract infection (UTI) due to a renal mass. Our radiological investigations indicated a Giant Schwannoma (GS), which emerged from the right L2 nerve root of 7.4x5.5x9cm in size. The tumor was seen extending from L1 to L4 and pressing on the kidney and ureter. The tumor excision was performed using the posterior and retroperitoneal approaches. It was diagnosed as Schwannoma histopathologically. No postoperative complications or recurrence was observed at follow-up of 6 months.
