Suprasellar meningioma 47 years after bilateral retinoblastoma

Development of an additional primary tumour, a suprasellar meningioma, is reported 47 years after successful treatment of bilateral retinoblastoma. The left eye of the patient was enucleated at the age of 1.5 years and the left orbit radiated with a total dose of 1200 rads. The right eye was treated by orthovoltage radiation only at the age of 4 years, the total dose being 5100 rads. The right eye became blind and phthisical, and it was enucleated at the age of 42 years. No active retinoblastoma was found. At the age of 48 years a large suprasellar meningioma was diagnosed and partially removed.
