Abstract:
A 14-year-old girl who had been experiencing ear discharge for the previous 3 years was referred to a tertiary care center for management of a 3-day history of severe headache and vomiting. Otolaryngologic examination revealed the presence of an atticoantral type of ear disease on the left side. Computed tomography detected an interhemispheric subdural abscess that had originated on the left side. The patient was initially treated with antibiotics, and she later underwent a mastoidectomy to clear the ear disease. She recovered without complications. Subdural empyema is the rarest complication of otitis media, and it is very rarely seen in an interhemispheric setting.
