The initial CT scans showed normal or brain contusions accompanied by a Me hemorrhage in 23 patients, and delayed intracranial hematomas developed after the earlier neurosurgical operations for evacuations of another traumatic mass lessions for urgent decompressions in 13 patients. Delayed hematomas occurred mostly in the acute stage of head injuries and most patients were impacted occipitally. Deterioration of consciousness was the most important manifestation for diagnosis. The responsible mechanisms of delayed intracranial hematomas are investigated and the indications of repeat CT scans or surgery for its early diagnosis are Droposed.
