Abstract Objective: Imaging features of intraspinal malignant peripheral nerve sheath tumors(MPNST) was studied in order to increase diagnose level. Methods: We analyzed retrospectively the clinical manifestations, pathological and imaging features of four intraspinal MPNST patients who were proved pathologically, and reviewed related literatures at the same time. Results: The lesions of all four cases presented as heterogeneous solid mass. The bigger ones were partially in the vertebral canal side with adjacent intervertebral foramen, which were across the canal. The shape of tumors were dumbbell-like or oval with clearly boundary and obviously heterogeneous enhancement on MRI. Conclusion: MRI is of great value in the diagnosis and differential diagnosis of intraspinal MPNST.
