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.

A Rare Case of Spontaneous Pneumocephalus as a Complication of Nontraumatic Nasal Liquorrhea

“…The term "spontaneous pneumocephalus" is applied to a state where air is accumulated intracranially regardless of any cause: tumor, infection, inflammation, surgery, or trauma [7] In this patient,…”

A Rare Case of Spontaneous Pneumocephalus as a Complication of Nontraumatic Cerebrospinal Fluid Rhinorrhea. An Evidencebased Review

“…В данном наблюдении представлен случай редко встречающейся спонтанной пневмоцефалии Тер-мин «спонтанная пневмоцефалия» применяется к состоянию, когда воздух накапливается интра-краниально независимо от какой-либо причины: опухоли, инфекции, воспаления, хирургического вмешательства или травмы [7]. У данной пациент-ки пневмоцефалия развилась на фоне спонтанной назальной ликвореи.…”

A spontaneous Pneumocephalus and Hyperpneumatisation of occipital bone and atlas vertebra: a case report.

“…The first case report of pneumocephalus was in 1741 by Lecat. (1,26) Its association with craniofacial trauma, neurosurgical or ontological procedures, (9,14,23,24) otomastoiditis,(5) or skull base tumours (21,27) is well known. Spontaneous pneumocephalus caused by a primary defect at the temporal bone level without association with pathological conditions or surgery is very rare.…”
