Colloid Cyst Patient Registry and Research

At Weill Cornell Medicine we have a colloid cyst patient registry, the largest known in the world, that directly feeds into clinical questions related to these cysts. Owing to the size of this IRB-approved registry (currently more than 250 entries), research is ongoing for questions that would otherwise be impossible to answer. Features related to natural history, neurocognitive impact, familial occurrence, and predictors of progression are some of the clinical questions being studied at this time.
