Case Report

Abstract

Introduction

Intracranial malignant peripheral nerve sheath tumor (MPNST) is exceedingly rare. Previously reported cases of intracranial MPNST have been associated with development within a prominent cranial nerve.

Methods

This is the first report of an MPNST with both nerve sheath and vascular phenotype that follows the neurovascular bundle, without arising in a major cranial nerve or in the setting of neurofibromatosis type 1 (NF1).

Results

The patient is a 14-year-old boy with a history of worsening headaches for the past several months, left-sided hearing loss, nausea, vomiting, and vertigo. MRI was performed that demonstrated a large extra-axial tumor compressing the left infratemporal posterior temporal region. The tumor was associated with significant destruction of the superior portion of the petrous bone and extension through the petrous into the upper posterior fossa, immediately below the tentorium. The patient underwent surgical debulking and adjuvant chemotherapy with doxorubicin and ifosfamide. Pathology demonstrated a variant malignant peripheral nerve sheath tumor with both nerve sheath and vascular phenotype by immunostains. The patient’s symptoms improved following treatment.

Conclusion

We present the first reported case of an intracranial MPNST variant that developed along the neurovascular bundle as a sarcoma with both nerve sheath and vascular phenotype through the petrous bone and not associated with a major cranial nerve or with stigmata of neurofibromatosis type 1 (NF1). Although this is an extremely unusual presentation due to location and lack of prominent cranial nerves in that location, it is not unusual for benign nerve sheath tumors to follow the neurovascular bundle through foramen of cortical long bone or pelvis. This case suggests that physicians should incorporate intracranial MPNST variant into their differential diagnosis in the cranium, even when tumor is not located near a prominent cranial nerve. Surgical debulking and adjuvant chemotherapy with doxorubicin and ifosfamide has led to improvement in patient symptoms.
