Abstract

Brain vascular malformations are recognized as having potential to produce hemorrhage, but leading to sudden death in children is uncommon. Arteriovenous malformations may be situated in any region of the brain, but very rarely, they can be restricted to the choroid plexus. We report here a rare case of sudden death in a child, caused by a ruptured vascular malformation with an unusual location, which was not identified grossly but only on histological examination. The size and the location of the lesion, as well as the age of our patient, were contributing factors of the massive bleeding. Autopsy remains an important tool because it provides valuable information about the etiology of such bleedings, improves knowledge about these lesions, and enhances epidemiologic data.
