[Pneumocephalus as a complication of mastoid surgery].

Non-traumatic otologic diseases are a rare cause of pneumocephalus. Among them, few reports have been described whereas it occurred following oto-surgery. We present a case report of pneumocephalus in a patient who presented with CSF-otorrhea, headache, disorientation, after recent mastoid radical surgery. The definite diagnosis was done by CT scan imaging. We realize a review of the literature about this subject, we describe the clinical and diagnostic features, its possible physiopathology, and its surgical management.
