Sinus barotrauma leading to extradural muco – pneumocephalus

Abstract

An amateur scuba (Self Contained Underwater Breathing Apparatus) diver experienced an acute frontal headache following a low-depth dive. After 12 hours of worsening and unremitting headache, CT and MRI imaging were performed; these revealed gas and mucous in the frontal sinus and extradural space. This appears to be the first case of MRI-documented barotrauma of the frontal and ethmoidal sinuses resulting in extradural pneumo- and muco-cephalus.

Key words:

• Sinus barotrauma
• extradural collection
• diving injury
