Abstract
Background: Subdural empyema is an extremely rare and fatal intracranial complication of chronic otitis media. Due to its rarity and vague symptoms it is often diagnosed late if not completely missed; specially in developing countries where the diagnostic modalities are hardly available or accessible. To the best knowledge of the authors, this is a preliminary reported case of a subdural empyema as a complication of chronic otitis media in Eritrea, aiming to inform on the clinical presentation, preferred diagnostic modalities, and the proper management of such cases.
Case Report: An eight years old female patient presented with fever, right ear purulent discharge, right post-auricular swelling, and altered mental status of two weeks duration. Prior to her admission, she had history of recurrent purulent discharge from her right ear for almost 2 years, and had been diagnosed with chronic otitis media. Upon admission her GCS was 13/15 which later on deteriorated to be 3/15 on day three. MRI was done which showed a right fronto-tempo-parietal subdural empyema with mass effect, shifting the midline to the left. She was immediately started on broad spectrum antibiotics empirically. After the diagnosis was made, craniotomy was done, and 30ml of pus was removed from the subdural space. Culture and sensitivity of the pus obtained intraoperatively was done but produced no yield. Hence, she was continued on the empirically started antibiotics. The patient’s condition was well improved by post-operative day 4.
Conclusion: It is important to have a high index of suspicion of intracranial complications in patients with history of chronic otitis media or other otologic symptoms, and neurologic manifestations. Subdural empyema still being uncommon even among the intracranial complications of COM, it is often missed. Hence, timely diagnosis with MRI, immediate surgical evacuation of the empyema with the prolonged administration of broad spectrum antibiotics is suggested.
