In the clinical diagnosis the major signs were local injury, occipital fracture, deterioration of consciousness and impaired respiration. CT scan enables prompt diagnosis. Fifteen cases took an acute course. Epidural clots in 12 patients were extended upwards above the lateral sinus and torcular. Three patients had associated surgical intracranial lesions: cerebellar haematoma in two, and supratentorial acute subdural haematoma in one.
