A Rare Case of Tension Pneumocephalus with Spontaneous CSF Rhinorrhea Managed by Endoscopic Trans-Sphenoidal CSF Leak Repair.

Tension Pneumocephalus and spontaneous CSF rhinorrhea are very rare associations in clinical practice. We report a case of 65 years old male with clear rhinorrhea, severe frontal headache, vomiting and lethargy for a week. MR Cisternography and CT Paranasal sinuses showed significant Tension Pneumocephalus with defect in the posterior wall of sphenoid sinus and CSF pooling in the sphenoid sinus. Endoscopic trans-sphenoidal CSF leak repair was done without any delay followed by complete resolution of Tension Pneumocephalus with in 4 post op days. Prompt precise diagnosis and early intervention of Tension Pneumocephalus is vital to avoid neurological complications.
