title: Spontaneous Resolution of a Large Chronic Subdural Hematoma Which Required Surgical Decompression.
abstract: We report on a case of an 87-year-old woman who showed spontaneous resolution of a large chronic subdural hematoma which required surgical decompression. She had suffered from confused mentality and right side weakness of motor grade II for 10 days. The initial brain CT scan showed a 22 mm thick low density lesion located in the left fronto-temporo-parietal region with midline shift (12 mm) which required emergency decompression. However, because she and her family did not want surgery, she was followed up in the outpatient clinic. Five months later, follow up brain CT showed that the CSDH had disappeared and the patient became neurologically normal. The reasons for spontaneous resolution of CSDH remain unclear. We discuss the possible relation between mechanisms of physio-pathogenesis and spontaneous resolution of a large chronic subdural hematoma (CSH) in an elderly patient.
