Metastatic malignant peripheral nerve sheath tumour presenting as a spontaneous extradural haematoma - A case report.

Malignant peripheral nerve sheath tumours may arise from any cranial or somatic nerve. The median survival with best therapy is 49 months. The present case reports a patient with an MPNST that exhibited an unusually indolent behaviour. Besides this, the patient developed a dural metastasis from the lesion and presented with a spontaneous extra-dural haematoma. This has not been reported hitherto in literature.
