A 51-year-old man with a history of a fall from a height 12 days earlier, treated at another hospital, presented now with a sudden onset loss of consciousness. The Computed Tomography (CT) of the head revealed tension pneumocephalus (TPC) [[Figure 1], Panel A]. An emergency twist-drill craniostomy released a puff of air and a subdural drain was placed with an underwater seal., On enquiring, the patient had a history of right-sided Cerebrospinal Fluid (CSF) otorrhea for the previous three days. CT at the time of the fall showed a right parietal thin Extradural Hematoma (EDH), left frontal and temporal contusions, right temporal bone fracture, and there was no evidence of pneumocephalus. An Magnetic resonance imaging (MRI) performed 36 h post-admission revealed left posterior cerebral artery territory infarct with hemorrhagic conversion [[Figure 1], Panel B and C] and MR cisternogram revealed no active CSF leak. He gradually regained consciousness after 48 h of admission. The subdural catheter drained CSF for 3 days and there was a resolution of pneumocephalus and CSF otorrhea [[Figure 1], Panel D] Delayed post-traumatic CSF otorrhea can be a potential cause of TPC, which can present as a stroke. Tension pneumocephalus is a very rare cause of ischemic infarct. This is the second case of TPC in the literature presenting with stroke, while in another case, TPC developed following endoscopic sinus surgery. Raised intracranial pressure due to the pneumocephalus can result in trans-tentorial herniation leading to an infarct. An early evaluation and appropriate intervention are warranted to bail out of this life-threatening emergency.
