COMPLETE or partial agenesis of the corpus callosum is uncommon especially in adults; the incidence amongst patients in institutions where numerous air encephalograms are performed is 3% (Carpenter and Drukemiller, 1953). Reil (1812) published the first report of a case, describing the necropsy findings in a 30 year old woman of low mentality; further cases discovered at necropsy were subsequen...

A patient with spontaneous periodic hypothermia who had both a lipoma and agenesis of the corpus callosum is described. Spontaneous periodic hypothermia associated with corpus callosum abnormalities is a distinct entity and although the mechanism underlying the hypothermic episodes is unexplained, the term "diencephalic autonomic epilepsy" does not seem appropriate.

basal encephalocele is a rare craniofacial anomaly. in the present paper we report a 10-year-old boy presented with cleft palate, congenital nystagmus, and hypertelorism. during preoperative evaluation for cleft palate repair, a pulsatile mass was detected in the pharynx. magnetic resonance imaging showed sphenoethmoidal type of basal encephalocele and agenesis of corpus callosum. neurosurgical...

Agenesis of the corpus callosum may be diagnosed successfully in vivo when sonograms demonstrate absence of corpus callosum; absence of pericallosal and cingulate sulci; "sunburst" pattern of sulci along the medial surface of the hemisphere; wide interhemispheric fissure; elevation of the third ventricle; small, laterally positioned frontal horns with concave medial borders; large, laterally po...
