Tetralogy of Fallot: Stroke in a Young Patient.

Tetralogy of Fallot (TOF) is a congenital birth defect of the heart which actually comprises four individual flaws. It causes poor flow of oxygenated blood to the organs and leads to cyanosis (blue-tinted skin, because of inadequate oxygenation). It can be recognized at birth or in adulthood. But sometimes, cases may go unnoticed, and the patient might present with some rare complications. In this case, the patient presented with an embolic infarct of the brain at the age of 25 with an undiagnosed tetralogy of Fallot.
