Surgical Management and Functional Outcome of Primary Convexity Subdural Empyema With Inter-hemispheric Extension: A Case Report and Literature Review

Abstract Background:Subdural empyema is the collection of pus beneath the dura matter, commonly manifests as a complication of oto-rhino-laryngeal infection and rarely locates in the inter-hemispheric subdural space either as an isolated collection or as extension from the convexity of the cerebral hemisphere.Case presentation:A case of right fronto-parietal convexity subdural empyema with inter-hemispheric extension in 19 years old male is presented patient presented with fever, left sided convulsions, hemiparesis and blurring of vision. Despite the use of broad spectrum antibiotics based on cultures, surgical intervention with craniotomy was the definitive intervention needed for good recovery.Conclusion:Subdural empyema located in inter-hemispheric area represents rare form of subdural empyema. The best investigation to choose to diagnose these lesions is definitely magnetic resonance imaging of the brain .craniotomy is the surgical intervention of choice in most of the cases and almost lead to complete evacuation of the collection followed by the use of empirical antibiotic for six weeks duration, both means of treatment are used in order to reach better functional outcome.
