Mega Corpus Callosum in a Patient with Macrocephaly and Focal Motor Delay

Abstract

An enlarged corpus callosum is a rare entity, with extremely low rates documented in literature. When paired with macrocephaly, only a handful of cases without any other underlying systemic condition are known to exist. We present a novel case of a macrocephalic patient with magnetic resonance imaging findings of an enlarged (or mega) corpus callosum. Neurologic exam demonstrated right lower extremity hypertonicity without any other developmental disorder. It is important to be aware of an enlarged corpus callosum as it may be associated with an underlying motor disorder.
