Thirty-one adult patients with chronic subdural hematoma were treated surgically and followed Up by CT. In these cases, the postoperative regression of the hematoma cavity on CT was analysed in relation to patient's age, timing of operation, operative method, preoperative CT findings and postoperative clinical courses. In patients with older age and/or low density type of hematoma, slow reduction of subdural space was observed after operation. In five of these cases, the follow-up CT scans revealed reaccumulation of hematoma. Patients with high density type of hematoma and/or early operation from the onset showed a rapid reduction of hematoma cavity and clinical improvement.
