Abstract

Brainstem hemorrhage in descending transtentorial herniation is well known as Duret hemorrhage. However, CT or MRI rarely reveals Duret hemorrhage. The authors report a case of brainstem hemorrhage after craniotomy of spontaneous acute subdural hematoma. A 47-year-old man suffered sudden onset of severe headache and progressive consciousness disturbance. Initial CT scan demonstrated a right acute subdural hematoma and a marked shift of the midline structures to the left. Emergency craniotomy was performed but he remained comatose. CT scan after 8 days showed multiple petechial hemorrhages in the brainstem. We reported a rare case of Duret hemorrhage diagnosed by CT scan. Duret hemorrhage is almost fatal.
