"Trilateral retinoblastoma" (TRB) is the association of a midline intracranial tumor with familial bilateral retinoblastoma. Classically, the intracranial tumor is a pineal region tumor (pineoblastoma) with histology similar to retinoblastoma. ⋯ The presentation and prognosis of patients with this association differ from those children with "classical" TRB. The presentation, treatment, and outcome are described, with a review of the literature.
