Abstract

Interpeduncular heterotopia is a new neuroimaging finding reported in association with Joubert syndrome (JS) in a few cases in the literature. Nodular interpeduncular tissue was termed as interpeduncular heterotopia and anterior mesencephalic cap dysplasia in the literature in relation to gray and white matter content. We described the imaging findings and diffusion tensor imaging data of a case with interpeduncular heterotopia and brain stem cleft. This is the first case, in which interpeduncular heterotopia was an isolated finding not associated with JS.
