  • Abstract
  • Look Inside

A 70-year-old man was suffered from recurrent serous otitis media for 2 years. There was no history of head trauma, infection, or ear surgery. AlthoughCT scan demonstrated no distinct tegmen defect, glucose of the middle ear fluid was positive, suggest-ing cerebrospinal fluid. After confirmation of CSF in the middle ear fluid by beta-2 transferrin, middle cranial fossa craniotomy was performed for the treatment of CSF leak. Two small pieces of granula-tion like tissue originated from brain penetrated the roof of tympanic cavity. The tissue was confirmed as brain tissue histologically. The fistula was closed by a temporal fascia graft with preservation of hearing.
