Schwannoma of the kidney is exceedingly rare. We describe contrast-enhanced CT and FDG PET/CT findings in a case with renal cellular schwannoma. Contrast-enhanced CT showed the enhancing tumor was located in the anterior middle portion of the left kidney, encasing the renal vessels and compressing the renal pelvis. The tumor showed inhomogeneous FDG uptake with SUV max of 8.6 mimicking renal cell carcinoma. This case indicates renal schwannoma should be included in the differential diagnosis of FDG-avid renal lesions.
肾脏施万细胞瘤极为罕见。我们描述了一例具有肾脏细胞施万细胞瘤的病例的增强 CT 和 FDG PET/CT 表现。增强 CT 显示，肿瘤位于左肾前中部，包绕肾血管并压迫肾盂。肿瘤表现为不均匀 FDG 摄取，SUVmax 为 8.6，类似于肾细胞癌。本病例表明，在 FDG 摄取的肾脏病变的鉴别诊断中应包括肾脏施万细胞瘤。
