Subdural Hemorrhage Mimicking Relapse in a Patient with Multiple Sclerosis

Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system, which is more common in young adults and can present with various clinical manifestations. The emerging neurological findings in the course of MS are often considered as relapses; however, neurological deterioration may have other treatable causes than relapses. No data are indicated in the increased frequency of the overall hemorrhagic stroke in individuals with MS, thus the coexistence of MS and subdural hematoma has been rarely reported. This study presents a 49-year-old male patient with a subdural hematoma that mimics a relapse. Recently emerging neurological symptoms in the course of MS frequently indicate a new demyelination event; however, emerging neurological symptoms may have other treatable causes besides relapse, especially in the presence of red flags such as headaches.
