Spontaneous pneumo-cephalus caused by otogenous temporal abscess

Area of Science:

• Neurology
• Neurosurgery
• Otolaryngology

Background:

• Otogenous abscesses, infections originating in the ear, can rarely lead to intracranial complications.
• Pneumocephalus, the presence of air within the cranial cavity, is an uncommon but serious consequence of head trauma or surgical procedures.

Observation:

• The authors present a unique case of spontaneous intraparenchymal and intraventricular pneumocephalus.
• This condition arose from the external rupture of a temporal bone abscess of otogenous origin.

Findings:

• The spontaneous rupture of an otogenous temporal abscess directly led to air entering the brain parenchyma and ventricular system.
• This case highlights an unusual pathway for the development of pneumocephalus, distinct from typical traumatic or iatrogenic causes.

Implications:

• Understanding this rare etiology is crucial for diagnosing and managing similar complex neurological presentations.
• This case underscores the importance of considering otologic sources in the differential diagnosis of intracranial air.
