Abstract
We encountered a case of perilymph fistula with brain tumor. A 14-year-old female complained of right hearing loss and dizziness after blowing her nose. An audiogram showed right deafness and we diagnosed perilymph fistula. After admission, she was confined to bed rest and treated with steroid therapy. Dizziness diminished, but deafness persisted. After one month, she returned to our hospital because of right facial palsy, ataxia and right hemiparesis. Her consciousness was drowsy. CT and MRI showed a 5 cm brain tumor. She underwent surgical removal of the tumor by neurosurgeons. The surgical specimen demonstrated medulloblastoma. Her conscious cleared but she later developed postoperative cerebrospinal fluid otorrhea and rhinorreha, in addition to dizziness. Recurrence of the perilymph fistula was diagnosed. Surgery was performed to perilymph fistula. After the second surgery, her dizziness and hearing loss were recovered.
