Multiple disparate cranial neoplasms.

The case of a three-year-old girl with fibrosarcoma of the right orbit is presented. She was initially treated with surgery and later with radiotherapy. After an interval of thirty-three years she developed a suprasellar epidermoid cyst and two years later a right frontal meningioma. The two benign tumors fulfill the usual criteria for irradiation induced tumors and the possible role of radiotherapy in their induction is discussed.
