Complete agenesis of the corpus callosum but persistant hippocampal commissure: Differential diagnostic criteria

Journal article

Agenesis of the corpus callosum is mostly observed in the context of maldevelopmental syndromes and associated with further structural abnormalities. The callosal defect may be partial or complete. Other than the absence of the corpus callosum itself, indirect criteria may help in the identification of callosal malformations. We report on a patient with complete callosal agenesis, who had a persistant hippocampal commissure. This fiber tract may cause diagnostic difficulties but can reliably be identified if the morphology of the hippocampus and the indirect signs of callosal agenesis are taken into consideration.
