Bilateral acoustic neuromas are noted expanding the internal acoustic meati and extending into the cerebellopontine angles in keeping with neurofibromatosis type 2.
There is also an enhancing presumed schwannoma within the horizontal portion of the right facial canal in keeping with a facial nerve schwannoma. Bilateral trigeminal schwannomas are noted, on the right side this extends slightly through the foramen ovale. Further schwannomas are demonstrated related to the cranial nerves. Notably there are small bilateral oculomotor nerve schwannomas as well as an enhancing focus in the prepontine cistern on the right likely an abducens nerve schwannoma.
Enhancing lesions are also noted along the course of the lower cranial nerves extending towards the jugular foramina in keeping with further lesions. Enhancement is noted centred on the central canal of the visualised upper cord, likely an ependymoma.
A meningioma is noted predominantly inferior to but also extending around and superior to the left tentorium cerebelli with associated dural thickening. It compresses the quadrigeminal plate cistern, fourth ventricle and distorts the midbrain / cerebral aqueduct but without hydrocephalus. Further small meningioma is noted overlying the right frontal lobe. Bony thickening is noted in the left frontal bone near the coronal suture but no definite associated meningioma identified in this region.
