title: Spontaneous otogenic pneumocephalus presenting with occipital subcutaneous emphysema as primary symptom: could tension gas cause the destruction of cranial bones?
abstract: The authors report, to the best of their knowledge, the first case of a spontaneous tension pneumocephalus with subcutaneous emphysema. Hyperpneumatization of the cranium and mechanical compression contributed jointly to the formation of a fistula, and air pressure caused a subsequent disruption of the suture and air leakage into the subcutaneous space. A minimally invasive otological procedure proved efficacious for resolution.
