J Al-Watban, M Banna, Infantile Cardiomegaly as a Complication of Vascular Malformations of the Brain: Report of Two Cases. 1988; 8(5): 373-376 Congenital heart diseases constitute the main cause of cardiomegaly in the neonatal period. Extracardiac arteriovenous communications are an exceedingly rare precipitating cause of heart disease. We have encountered two cases of cardiac enlargement secondary to intracranial arteriovenous shunts and wish to draw attention to this situation.
Case Reports Case 1A 7-month-old boy was referred to King Faisal Specialist Hospital (KFSH) for evaluation of hydrocephalus. On clinical examination, the child was obviously hydrocephalic. He was very weak and could not support himself in the sitting position, nor could he roll over on his own when he was positioned flat on the examination table. His tendon reflexes were all brisk. A chest roentgenogram showed generalized cardiomegaly (Figure 1).Computed tomography showed a massive aneurysm of the vein of Galen (Figure 2), which was confirmed angiographically. A ventriculoperitoneal shunt was inserted for the treatment of hydrocephalus with the view that surgery might be considered at a later date.
Case 2A 7-year-old girl was referred to KFSH because of epilepsy and severe mental and physical retardation. Prior to her referral, she was investigated in another hospital, where CT and magnetic resonance imaging (MRI) of the brain showed a large vascular malformation (Figures 3, 4).
