Pituitary duplication associated with oral dermoid and corpus callosum hypogenesis

Abstract

We report a case of pituitary duplication in a neonate girl whose magnetic resonance (MR) images showed unusual findings of hypogenesis of the corpus callosum and oral dermoid. Pituitary duplication is an extremely rare malformation, with only a few previously reported cases. It occurs most commonly in association with complicated midline and skull base anomalies. We present a case of this malformation with special emphasis on the hypogenesis of splenium of the corpus callosum and oral dermoid. © Springer-Verlag 2004.
