Cerebral aneurysms in children.

This group of 22 children has illustrated the unusual nature of congenital and acquired cerebral aneurysms versus those found in adults.The identification of cerebral aneurysms in the first decade of life has resulted from the increased use of cerebral angiography in children.The unexpected large size of our congenital aneurysms is contrary to the expected small size dictated by accepted pathogenetic concepts.The anatomic distribution of congenital aneurysms is different from those of adults, and only the internal carotid bifurcation can be implicated as a common point of origin.Current selective angiographic techniques promise an increased incidence and accuracy in the diagnosis and demonstration of cerebral aneurysms in infants and children.
