The Unspoken Danger of the Mount Fuji Sign Leading to Sudden Death.

Traumatic pneumocephalus is not an unusual entity. Mostly, such cases are managed according to the patient's neurological status, guided by computed tomography (CT) imaging, and the patient responds well to conservative treatment. However, it seldom progresses to tension pneumocephalus, and if it does along with deterioration of the neurological condition, then neurosurgical intervention becomes necessary. On CT, its appearance is named "Mount Fuji" sign. The most widely documented peril involves increased intracranial pressure causing mass effect and, in some cases, cerebral herniation. However, one unspoken aspect leading to sudden death is seizure. We report the case of a 52-year-old male, admitted after vehicular accident responding well to the conservative treatment along with resolution of tension pneumocephalus. However, he developed generalized tonic-clonic seizures leading to sudden death. Through this case report, we will be discussing the association of pneumocephalus with seizures and seizures leading to sudden death.
