The authors report a case of intehemispherical fissure archnoid cyst with agenesis of
the corpus callosum who was 11-year-old child suffering from partial seizure. The
interhemispheris area is a rather uncommon site for arachnoid cysts. Carefull analysis of
the anatomical and radiological features of this case seems to suggest that two
morphologically distinct types of cysts occurred in the interhemispheric area : (1)
Interhemispheric cyst associated with agenesis of the corpus callosum (2) parasagittal
cyst. not associated with such an anomaly. The interhemispheric fissure arachnoid cyst
occurs in the middle, stradding the falx, and extends about equally on either side.
Compressing the medial surface of both hemispheres. A coronal CT or MRI view shows
a 'batwing' appearance of the lateral horns and dorsal displacement of the third
ventricle. It should be stressed that a histologically heterogenous group of
cysts(ependymal, glial, choroid eithelial, and arachonoid) may give rise to this same
morphologic appearance. The anterior intehemispheric approach was performed and
removal of cystic membrane was achieved. Postoperatively, there was no focal
neurological deficit.
