Focal luxury perfusion with an early-filling vein in relation to neurological symptoms evoked by heat.

A 50-year-old man with a 1-year history of transient attacks of left total hemiparesis was admitted to hospital with a complaint of increasing frequency of attacks. Minimal or moderate left hemiparesis was elicited by elevation of environmental temperature when taking a hot bath or a hot shower. Right carotid angiography revealed an early-filling vein near the right central sulcus. An increase of focal luxury perfusion by elevation of body temperature seemed to cause relative ischaemia in this paracentral gyrus.
