The trilateral retinoblastoma syndrome.
We present two cases of bilateral retinoblastoma with intracranial tumour, in the pineal region in one cases and in the suprasellar region in the other. We agree with Zimmerman and others that the intracranial tumour represents ectopic foci of retinoblastoma rather than metastatic spread. We suggest that CT scanning should be part of the assessment of all cases of bilateral retinoblastoma.
