title: Atypical presentations in Chiari II malformation.
abstract: Myelomeningocele with Chiari II malformation and hydrocephalus is a common association seen in infants with a congenital failure of neurulation. Here we report two cases of such an association presenting with different sets of problems. The first patient presented with severe inspiratory stridor due to bilateral abductor vocal cord paralysis, which was relieved completely within 24 h of definitive surgery. The second patient experienced intraoperative cardiac arrest. Definitive surgery was followed after successful cardiopulmonary resuscitation. The cause of the perioperative sequence of events in both cases is attributed to the associated pathologies of Chiari II malformation.
