Sudden infant death due to asplenia syndrome.

An apparently healthy 80-day-old boy died suddenly for no apparent reason. The autopsy revealed that the patient had had congenital asplenia, extensive cardiovascular anomalies, and other organ malformations, including trisegmented lungs, hypoplasia of the corpus callosum and cranial bones, a symmetrical liver, accessory hepatic tissue in the adrenal glands, malrotation of the intestine, and hypoplasia of the greater omentum.
