title: Symptomatic colloid cysts in the third ventricle of monozygotic twins.
abstract: In this case report we describe colloid cysts in the third ventricles of monozygotic twin sisters. They were 26 years old when their condition was discovered. One woman was admitted to us on an emergency basis, with signs of high intracranial pressure such as unconsciousness and extension posturing. Her sister was also brought to the hospital since she had a history of attacks of headache. They were both operated with removal of the colloid cysts, and the clinical courses are described in the case report. In reviewing the literature another 30 familial cases were found. Of these were two pairs of monozygotic and one pair of dizygotic twins.
