Aortic runoff as a sign of intracranial arteriovenous malformation: report of two cases.

BACKGROUND: Intracranial arteriovenous malformation rarely causes pulmonary hypertension and congestive heart failure in the newborn. Its diagnosis is challenging because cardiomegaly may suggest an intra-cardiac structural lesion. CASE PRESENTATION: We present two newborns, one 2-day-old male and the other 11-day-old female, with intracranial arteriovenous malformation and misdiagnosis of congenital heart disease. CONCLUSION: Precise echocardiography revealed the secondary signs of cranial arteriovenous malformation and had the major role in early diagnosis.
