Abstract

Background : As a complication of iron deficiency anemia, only a few cases of the infarction involving major cerebral artery territory area have been reported. Although the reactive thrombocytosis secondary to iron-deficiency anemia may be suggested as a cause, the exact mechanism is unclear. Until now, the sole possible level of thrombocytosis associated with iron deficiency anemia for cerebrovascular accident has been reported as more than 8.0 x 105/mm3. Case Description : We present a case of young woman with mild reactive thrombocytosis(5.95 x 105/mm3) secondary to iron deficiency anemia who developed left middle cerebral artery territorial infarction. We did not find any other precipitating factors despite of all possible etiological evaluations including cerebral angiography. After the treatment of iron supplement and antiplatelet agent, the recovery was relatively good and no definite neurological deficits were remained. Conclusion : We suggest that this large territorial infarction might be related to the severe iron deficiency anemia and the reactive thrombocytosis associated with iron deficiency anemia and the correction of anemia and antiplatelet therapy is a reasonable approach.
