Pneumocephalus is a rare condition characterized by the presence of gas within the
cranial cavity. This gas arises either from a trauma, tumor, surgical procedure, or
occasionally from infection. Pneumocephalus secondary to chronic otitis media is an
extremely rare phenomenon. We describe here a 70-year-old male, a known case of chronic
suppurative otitis media who presented with sudden onset severe thunderclap headache
and was eventually diagnosed as pneumocephalus.
Key-words:
Pneumocephalus - subarachnoid hemorrhage - thunderclap headache
