AbstractChronic subdural hematomas are typically observed in elderly patients receiving antithrombotic and/or anticoagulant therapy. In contrast, acute subdural and extradural hematomas are often observed in young people with traumatic brain injury. The coexistence of ipsilateral chronic subdural and extradural hematomas is rare. Depending on the Glasgow Coma Scale and neuroimaging findings, early surgical intervention is mandatory, as seen in our patient. Early surgical evacuation of a traumatic extradural and chronic subdural hematoma should be done. Also, antithrombotic drug use can lead to chronic subdural hematoma.
