title: Malignant schwannoma of the parapharyngeal space.
abstract: We present a case of malignant schwannoma (MS) of the parapharyngeal space which completely encircled the internal carotid artery in close proximity to the skull base and required resection of the internal carotid artery along with the excision of the tumour. There have been three previous case reports in the literature of malignant schwannoma of the parapharyngeal space of which one case was associated with neurofibromatosis. Our patient did not exhibit any feature of neurofibromatosis.
