Agenesis of the corpus callosum
R. B. Lynn, D. C. Buchanan, G. M. Fenichel and F. R. Freemon
A father and son with agenesis of the corpus callosum are described. An
11-year-old boy underwent clinical examination because of poor school
performance. On physical and mental examinations he was normal, except for
an enlarged head. Computerized tomographic (CT) scan showed agenesis of the
corpus callosum. The patient's father also had an enlarged head. Although
he had never had any symptoms, he underwent CT scanning, which revealed
agenesis of the corpus callosum. Psychological tests showed good
communication between the two cerebral hemispheres. All-night sleep EEGs
showed asynchronous sleep spindles.
