Subacute left hemispheric subdural hematoma associated with symptomatic contralateral hygroma

Subacute subdural hematoma associated with contralateral post-traumatic hygroma is a rare condition, especially in young patients without coagulopathy or anticoagulant use. This case report presents a 25-year-old female with a history of mild traumatic brain injury leading to left hemispheric subacute subdural hematoma and symptomatic contralateral hygroma. The report discusses the pathophysiology, including potential mechanisms such as bridging vein rupture and impaired brain expansion, risk factors, and management approaches. Surgical intervention for the subdural hematoma and contralateral hygroma resulted in rapid symptomatic relief with favorable clinical outcomes. This case highlights the importance of individualized management strategies and calls for further studies to standardize treatment guidelines for similar presentations.
