[Acute traumatic infratentorial subdural hematoma].

The case of an injured man, aged 54, is reported. On the basis of the neurological symptoms, without neuro-radiological contrast examinations, in presence of negative skull osteogram, on the day of the injury suboccipital craniectomy and removal of the subdural haematoma have been performed. The diagnostical difficulties of the occipital injury are pointed out, since both the occipital and infratentorial regions are "silent" regions for the carotis-angiography. In the case of subdural haematoma the suboccipital decompression performed in due time may be exactly as much successful as the supratentorial decompression.
