Spontaneous drainage of an infratentorial extradural empyema: case report.

We describe a 21-year-old male who presented with spontaneous drainage of an infratentorial extradural empyema secondary to mastoiditis. Following eradication of the primary source, the patient was commenced on high dose intravenous antibiotics. Serial computed tomography (CT) revealed complete resolution of the pus collection. Antibiotic therapy was successful and no neurosurgical intervention was necessary.
