Value of biplane computerized tomography in agenesis of the corpus callosum. A case history.

A case of agenesis of the corpus callosum is described in a 21-year-old male, presenting with epilepsy. Computerized tomographic (CT) scanning was performed using axial and coronal sections. The diagnosis of agenesis was suggested by the presence of an enormous third ventricle, the coronal sections gave the definite proof. In our opinion, biplane CT scan appearances in this condition are characteristic and former investigations (PEG, cerebral angiography) become unnecessary.
