Magnetic Resonance Imaging of Schwannoma

Abstract

Magnetic resonance imaging is useful for the diagnosis of bone and soft tissue tumors. We experienced 7 cases of schwannoma in peripheral nerves or cauda equina, which were treated by surgical extirpation. This study reports the correlation of MR imaging and pathologic findings of schwannoma. MR imaging reflected the pathologic view of the tumors, cyst and hemorrhage. Proton-density-weighted images were useful for imaging tumors in the spinal canal.
