Malignant peripheral nerve sheath tumor in spine: imaging manifestations.

Malignant peripheral nerve sheath tumor (MPNST) is a relatively rare soft tissue malignant tumor. Most of reports currently are pathological articles and clinical case reports and most of them are MPNST in the thorax, abdomen or extremities. Imaging report of spinal MPNST is very rare, and MPNST is easy to be misdiagnosed. In this study, we explored the computed tomography and magnetic resonance imaging manifestations of MPNST that occurred in the spine and to improve the preoperative diagnostic accuracy of MPNST.
