Abstract

Schwannoma is a benign nerve sheath tumor that involves Schwann cells mostly found in the head, neck, posterior mediastinum and extremities. Schwannoma develops rarely in the retroperitoneum; thus, renal schwannoma is extremely uncommon. Differentiation of renal schwannoma from renal cell carcinoma is difficult with radiologic analysis. A few cases of these tumors have been reported in literature, and little has been described regarding imaging appearances. In this study, we present a rare case of a renal schwannoma, resembling renal cell carcinoma, with radiological correlations.

신경초종은 양성 신경막 종양으로 신경집 세포로 구성되어 있으며, 주로 두경부, 전종격동, 상 하지에서 발생한다. 신경초종은 후복막강에서도 발견되지만, 특히 신장 신경초종은 매우 희귀하며 영상검사만으로는 신장세포암과 감별이 어렵다. 신장 신경초종에 대한 문헌 보고는 많지 않으며, 특히 영상 소견을 중심으로 기술된 경우는 드물다. 이번 증례에서 신장 세포암과 유사하게 보일 수 있는 신장 신경초종에 대하여 기술하고, 영상의학적 특징에 대한 문헌고찰을 함께 하고자 한다.
