Trans-foramen ovale biopsy of a parasellar lesion guided by intraoperative CT neuronavigation with MRI fusion: A case report

Abstract

A 23-year-old male presented with a parasellar lesion which was suspected as disseminated intracranial germ cell tumour. The diagnosis of germinoma was made using immunohistochemistry from percutaneous trans-foramen ovale biopsy. This report describes the role of neuronavigation-guided biopsy through the foramen ovale for lesions in the parasellar region.
