Cerebral infarction in sickle cell trait.

Sickle cell disease is known to predispose patients to the risk of cerebral infarction. However, only scattered reports exist of the neurological sequelae of the sickle cell trait. Only 8 cases are reported in the English literature, in some of which the sickle cell trait was not documented by hemoglobin electrophoresis. This report describes 2 men, age 35 and 24 years, who developed acute cerebral infarction. Investigation revealed no apparent cause for the lesion other than the sickle cell trait.
