[A case of schwannoma in the renal hilum].
A 58-year-old female presented with a well-encapsulated tumor in the left renal hilum on computed tomography (CT). On magnetic resonance imaging (MRI), the tumor showed low intensity on the T1-weighted image, high intensity on the T2-weighted image. Laparoscopic radical nephrectomy was performed because we could not exclude the possibility of malignancy such as renal cell carcinoma. Histopathological examination revealed that the tumor was a benign Schwannoma. Although renal hilum is a common site of renal schwannoma, it is difficult to differentiate benign tumors from malignant ones, and then nephrectomy is usually performed.
