Case contributed by Chris O'Donnell
Diagnosis certain

Presentation

Headache and neck stiffness post FESS for inflammatory paranasal sinus disease.

Patient Data

Age: 60 years
Gender: Male

Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.

Defect in the roof of the right anterior ethmoidal air cells with a fistula into the subarachnoid space indicating disruption to the dura. Gas has thus passed from the nasal cavity into the cranium via the ethmoidal air cells. 

Note the compression of this gas on the frontal lobes (arrows). This indicates mass effect and suggests that the gas (air) is under tension.

Case Discussion

Gross pneumocranium post functional endoscopic sinus surgery (FESS) for chronic paranasal sinus inflammatory disease.
