Bobble-head doll syndrome in an 80-year-old man, associated with a giant arachnoid cyst of the lamina quadrigemina, treated with endoscopic ventriculocystocisternotomy and cystoperitoneal shunt

Abstract

Bobble-head doll syndrome (BHDS) is a rare entity, characterized by antero-posterior head bobbing, which is of the type "yes–yes." Less frequently, having a head movement of the type "no–no" is described. We report an unusual case of an 80-year-old man with a cystic mass of the lamina quadrigemina, extending to the posterior fossa. We conclude that ventriculocystocisternotomy associated with a cystoperitoneal shunt is an effective treatment for a symptomatic giant arachnoid cyst in the lamina quadrigemina.
