Neurofibromatosis type II


The study reveals bilateral acosutic schwannomas which are highly suggestive of Neufibromatosis type II. Neurofibromatosis type II is also known as MISME syndrome for its association with multiple inherited Schwannoms, Meningiomas and Ependymomas, all of which are clearly delineated in this case. This patient has concurrent bilateral acoustic schwannomas, a cervical intramedullary ependymoma and falcine meningiomas. The large mass in right parietal lobe can be supratentorial ependymoma, priminitive neuro-ectodermal tumor or lymphoma. However, association with neurofibromatosis II and restricted diffusion on DWI strongly favors the diagnosis of supratentorial ependymoma.
