[A case of acute subdural hematoma in one-day-old baby--with special reference to its CT findings (author's transl)].
The authors describe and discuss a case of acute subdural hematoma originating from the lacerated tentorium of 22 hour-old newborn. CT scan revealed crescent high density area in the subdural space between the left frontal area and the occipital area. Another high density area was seen in the left occipital area which was suspected as intracerebral hematoma preoperatively because of its rather intramedullar location. Large craniotomy was performed 22 hours after delivery, evacuating 70 gm subdural hematoma. Bleeding point was determined as lacerated tentarium about 1 cm length. No intracerebral hematoma was found. Postoperative course was uneventful and he is showing normal development. It is now concluded that supratentorial subdural hematoma originating from tentorial laceration at delivery could be misdiagnosed as intracerebral hematoma on CT scan. Anatomical structure should be always compared when CT scan study is performed.
