title: Presentation of pinealoblastoma with ocular dipping and deafness.
abstract: Ocular dipping and deafness as presenting manifestations in a patient with pinealoblastoma are highly unusual. Presence of a discrete lesion allows us to postulate a mechanism to explain ocular dipping in light of the present understanding of vertical eye movement control. A mechanism for deafness, probably a false localizing sign of raised intracranial pressure, is proposed also.
