Chronic Subdural Hematoma in a Patient With Long-Standing Syphilis

Chronic subdural hematoma can rarely occur in younger adults without trauma or coagulopathy. Comprehensive imaging to exclude vascular malformations, combined with burr hole evacuation and middle meningeal artery embolization, can achieve excellent outcomes. Long-standing systemic infections may theoretically contribute to vascular fragility, but causality remains speculative.
