Radiation induced meningioma

Abstract

Introduction: The induction of neoplasms is a well-known, although rare, complication of cranial irradiation. Meningiomas are the most common radiation induced cranial neoplasms, followed by gliomas and sarcomas.

Objective: to present a case of radiation induced meningioma in an adult patient after receiving cranial radiotherapy.

Case presentation: a 34-year-old patient receives radiotherapy at the age of three due to a diagnosis of cerebral astrocytoma. After thirty years, he began with headache and focal convulsions, an intracranial mass lesion was studied and diagnosed, he received surgical treatment for resection of the lesion, and histological result of the lesion reported by Meningioma was received.

Conclusions: The development of neoplasms secondary to radiotherapy is a well-known phenomenon, the most frequent being meningiomas. Radiation induced meningiomas are characterized by presenting in young patients and patients treated with higher doses of radiation have a higher risk than cases of lower doses of previous radiation. Its most frequent location is in the convexity and base of the skull and most shows a certain degree of atypicality, which makes them more aggressive and have a higher rate of recurrence.
