Neurofibromatosis, type 2 with cerebrospinal fluid leak after surgery. Fluctuation of a sense of pressure in the head. There are postoperative findings related to bilateral middle cranial fossa cerebrospinal fluid leak leak repairs and right superior canal dehiscence repair. There is bone graft overlying the dehiscent right superior semicircular canal. The inner ear structures otherwise appear unremarkable. There is fluid within the left mastoid air cells. The bilateral cranial nerve 7 and 8 complexes appear to be intact, without evidence of mass lesions. There are unchanged bilateral petrous apex cephaloceles associated with enlarged Meckel caves and cystic dilatation of bilateral hypoglossal canal contents. There is also a partially empty sella.
1. Postoperative findings related to bilateral middle cranial fossa cerebrospinal fluid leak leak repairs and right superior canal dehiscence repair with persistent nonspecific fluid in the left mastoid air cells.2. Unchanged bilateral petrous apex cephaloceles and cystic dilatation of bilateral hypoglossal canal contents, which may be a sequela of elevated intracranial pressure, along with a partially empty sella.
