In the shadow of the cure: Radiation-induced intracerebellar cavernoma after successful retinoblastoma therapy

Radiation-induced cavernomas are rare. Even after years following radiotherapy for retinoblastoma, the possibility of an intracranial cavernoma cannot be ruled out. Imaging of the central nervous system may help detect these malformations, helping to initiate treatment early and hence, prevent life-threatening complications in such patients. We describe a case report of a female child who developed an intracerebellar cavernoma 14 years after irradiation for retinoblastoma. The purpose of this report is to add support to the growing literature that there is a possibility of the occurrence of cavernomas following radiation for retinoblastoma, the need for its timely diagnosis, and the importance of long-term follow-up in such patients.
