Malignant Peripheral Nerve Sheath Tumour : CT and MRI Findings

Abstract EN

Malignant peripheral nerve sheath tumour (MPNST) is extremely rare malignancy in the general population, occurring more frequently in patients with Neurofibromatosis type 1 (NF1).

In the literature five cases of MPNST arising from the parapharyngeal space (PPS) in patients without neurofibromatosis have been reported.

We report imaging techniques in a patient with MPNST in the PPS, who had neither a family history nor sign of NF1.

Computed tomography (CT) scan and magnetic resonance imaging (MRI) were performed for a correct therapeutic planning.

CT and MRI findings were correlated with hystopathological diagnosis.
