Atretic encephalocele
Alerts and Notices
Synopsis
Atretic encephaloceles occur most commonly in the parietal, occipital, or frontal region and may present with an otherwise benign-appearing subcutaneous nodule or mass. Alopecic lesions over the defect can occur as well. They have been associated with intracranial anomalies including interhemispheric cysts, abnormalities of the corpus callosum, ventriculomegaly, cystic malformations, and venous anomalies.
