Middle Interhemispheric variant (MIH) is a rare subtype of holoprosencephaly (HPE), also known as syntelencephaly. We present a case of MIH, which was diagnosed as an interhemispheric cyst on antenatal sonography at 19 weeks, but later diagnosed as MIH variant of holoprosencephaly after a postabortal MRI and perinatal autopsy.
