[Skull injury. Arteriovenous shunt. Limitations of cerebral x-ray computed tomography].

The authors report the case of a patient suffering from a head trauma after dizziness followed by a loss of consciousness. In the hours following the admission, he developed drowsiness and a left hemiparesis. CT scanner showed an intracerebral haematoma. Due to the dizziness a carotid angiography has been realized and has demonstrated an intracerebral avascular mass, an arteriovenous shunt and an epidural haematoma at the vertex. Two aspects of the case seem to be important: the first one is the limit of CT scanner; the second one is the relationship between the three lesions.
