Microsurgical management of giant malignant peripheral nerve sheath tumor of the scalp: two case reports and a literature review

摘要

Malignant peripheral nerve sheath tumors of the scalp are rare lesions of the nervous system. Only 14 cases have been reported to date. The field of neurosurgery has struggled with diagnosing and treating these tumors. In this report, we present two cases of giant malignant peripheral nerve sheath tumors of the scalp and retrospectively analyze the clinical features, imaging findings, pathological features, and prognoses of these two patients. Each underwent microsurgery and radiotherapy. In addition, based on a literature review, we discuss the diagnostic and therapeutic strategies used to treat these unusual lesions.
