Schwannomas are tumors originated from Schwann cells. Normally is located in the head, neck and limbs, but it can occur anywhere in the body where there are myelinated nerves. Renal involvement is rare, with few cases reported in the literature. The preoperative diagnosis is difficult, since it is based only on a specific clinical presentation and limited radiological resources. Although some MRI findings may raise suspicions for diagnosis, these tumors are often confused with renal cell carcinoma, with surgical resection as the standard treatment. Commonly require a pathological diagnosis. Although most cases exhibit benign behavior, malignant degeneration can occur. We report a case of tumor in the renal hilum, submitted to surgical resection, whose diagnosis of renal Schwannoma was confirmed histologically.
