ABSTRACT
Among cyanotic congenital heart disease, Fallot’s tetralogy most commonly presents in childhood and rarely goes beyond second decade as death is inevitable without surgical correction of the abnormality. Here we report about unusual course of an uncorrected tetralogy, in which patient reach adulthood and presented only with seizure later found to have brain abscess.Fallot’s tetralogy (TOF) accounts for 10% of cyanotic congenital heart disease, which has combinations of a) ventricular septal defect, b) overriding aorta, c) right ventricular hypertrophy, and d) right ventricular outflow tract obstruction.[1] Although known complication, cerebral abscess has been reported in patients with CHD mostly at the age of 4–7 years, only rarely in adults as their survival is minimal without surgical interventions.[2] In this case, a 49 year old female who presented with a cerebral abscess later diagnosed as TOF on 2 D echocardiography.
