Arthrogryposis Multiplex Congenita and Bilateral Parietal Polymicrogyria in Association with the Intrauterine Death of a Twin

Abstract

A case of neurogenic arthrogryposis multiplex congenita (AMC) with associated neuronal migration abnormalities is described. A child with neurogenic AMC and developmental delay presented with late onset of seizures. The first trimester of the mother's pregnancy was marked by an episode of gastro-enteritis and the intrauterine death of a twin fetus. Computer tomography (CT) and magnetic resonance (MR) imaging demonstrated abnormal neuronal migration consisting of bilateral parietal polymicrogyria, and an isolated grey matter heterotopia.
