We present the case of a 4-year-old girl with tetralogy of Fallot associated with an incidentally detected isolation of the left brachiocephalic artery, with no communication between it and the pulmonary artery or ductus arteriosus. The case highlights the unusual association and hemodynamic consequences of the condition.
Keywords: Computed tomography angiography; isolation of left brachiocephalic artery; tetralogy of Fallot.
