This article describes an 11-month-old Hispanic female patient with bi
lateral retinoblastoma (RB) and two distinct midline intracranial tumo
rs: (1) a large mass in the area of the pineal gland; and (2) a second
tumor in the suprasellar region. We believe both of the intracranial
tumors represent separate foci of a multicentric tumor. To our knowled
ge, this is the first reported case of two distinct midline intracrani
al tumors associated with bilateral RB, a condition we refer to as ''t
etralateral'' RB.
