An 18-year-old male presented with a 1-day history of seizures, fever, and altered level of consciousness. The patient had no prior history of seizures but had experienced breathlessness on exertion and spells of cyanosis since childhood. On examination, the patient had a Glasgow Coma Scale (GCS) score of 8/15, a temperature of 102°F, and was actively having tonic-clonic seizures. Signs of meningeal irritation were absent. Neuroimaging revealed multiple brain abscesses, and an echocardiogram confirmed an underlying diagnosis of Tetralogy of Fallot (TOF). This case highlights the uncommon but significant complication of brain abscesses in patients with cyanotic congenital heart disease.
