Axial T1-weighted postcontrast image of the orbit shows enhancement of the mass (arrow) of the right globe. The mass extends to the lens. Retinoblastoma is the most common tumor of the eye and children. Mutations of the RB1 gene are responsible for most cases of retinoblastoma. Approximately one-third of patients with retinoblastoma have a germline mutation. The remaining patients have a spontaneous mutation. #FridayQuizDay #FridayQuiz

Sagittal (image 1) and axial (image 2) T2 weighted MRI shows the large retinoblastoma (arrow) abutting the lens. Retinal detachment (arrow) head is present. Retinoblastoma is the most common neoplasm affecting the eye of the children. Retinoblastoma can be affected by a germline mutation. Thus, the radiologist should always look for disease within the contralateral globe. When evaluating the brain, other features to evaluate for include intracranial extension along the optic nerve, sites of intracranial disease, and complication such as retinal detachment.](https://app.figure1.com/case-detail/311bcc3b-b5fa-4627-b8dd-1584945e9e00)
