Sudden death in an infant caused by rupture of a basilar artery aneurysm.
Ruptured aneurysms of the cerebrovasculature in infancy and early childhood, except for "giant" aneurysms and arteriovenous malformations, are rare. Seizures, loss of consciousness, and apnea are the usual presenting signs in infancy; symptoms such as headache or visual disturbances and signs such as cranial nerve compression or meningeal irritation commonly found in older children or adults are absent in infants. However, the morphologic findings (i.e., subarachnoid and retinal hemorrhage, and occasionally subdural hemorrhage) may be mistaken for inflicted trauma, especially if the aneurysm is not identified. Sudden death caused by rupture of a cerebral aneurysm has not been previously described in an infant. This report outlines the investigation and autopsy findings in a 7-month-old infant who died unexpectedly as a result of rupture of a complex basilar artery aneurysm.
