[Corpus callosum agenesis and parasagittal interhemispheric cyst].J Radiol. 1996 Jun; 77(6):427-30.JR
We report the association of a corpus callosum agenesis with a parasagittal interhemispheric cyst, without cortical malformation. This rare malformation is related to an early disorder in embryogenesis. The importance of the anatomic abnormalities compared with the good clinical status is remarkable. MR findings avoid misdiagnosis with a medial interhemispheric cyst associated to corpus callosum agenesis in which the prognosis is unpredictable.
