[Ischemic, an uncommon complication of Biermer disease (pernicious anemia)].
BACKGROUND
Stroke in a young adult justifies an extensive etiologic workup.


METHODS
We present a 44-year-old women victim of a frontal ischemic stroke. Extensive evaluation was normal, except for high plasma level of homocysteine in the context of pernicious anemia, otherwise asymptomatic.


CONCLUSIONS
Hyperhomocysteinemia is a known marker, and probably risk factor for stroke, fostering atherosclerosis and thrombosis. It can be found among individuals suffering from homocystinuria, in individuals homozygous for the MHTFR T allele but also when there is deficiency of vitamin B12 or folic acid. Although it is very seldom ascribed, pernicious anemia would be a cause of stroke, possibly though hyperhomocysteinemia.
