[Hemiplegia during carbon monoxide poisoning revealing multiple cerebral artery abnormalities including the hypoglossal artery].
Hemiplegia after carbon monoxide (CO) poisoning is rare since only 9 such lesions have been reported from among 1480 cases of poisoning. The patient reported was a 43 year-old man with a left hemiplegia with coma following CO poisoning. Right carotid angiography demonstrated a hypoglossal artery supplying both posterior cerebral arteries. Left carotid angiography showed a dolichocarotid artery supplying the territories of the anterior and middle cerebral arteries on both sides. Complete regression of the hemiplegia occurred after 2 months following rapid administration of hyperbaric oxygen. Normal CT scan images and cerebral blood flow rates on follow-up examination suggest that the left hemiplegia was due to the combined effects of arterial anomalies and CO poisoning.
