A 29-year-old woman was found lying unconscious in the shower. There was a two-day history of headache and dizziness. In the emergency room, she was initially stuporous (Glasgow Coma Scale 10/15), afebrile, bradycardic and hypertensive. She exhibited roving, conjugate eye movements, left facial paresis (including frontalis), left ptosis, diffuse hypotonia, extensor plantar responses bilaterally and a 1.5 cm warm, fluctuant mass with surrounding erythema behind the left ear (Figure 1). Otoscopy revealed a bulge in the posterior wall of the left external auditory canal.
