Abstract
The chronic subdural hematoma is common traumatic lesion of head injury. The incidence of chronic subdural hematoma estimated 1-2/100,000 per year. And the causes, clinical characteristics, and therapeutic management are well established. And chronic subdural hematoma with multi-layer hematoma membrane was also usually reported. But it's etiology, characteristics, management of still have remained obscure. We report a case of a 60-year-old man, who complained of gait disturbance and voiding difficulty. Computed tomography (CT) scan revealed chronic subdural hematoma with multi-layer hematoma membrane. Burr hole craniostomy was performed 2 times, but sign and symptom was still remained and CT scan revealed reaccumulation of hematoma. Craniotomy was performed 2 times and multi-layer hematoma membrane was totally removed. Follow-up CT scan did not show reaccumulated hematoma.
