title: Retinoblastoma and simulating lesions: role of CT and MR imaging.
abstract: Diagnosis of retinoblastoma is one of the most challenging problems of pediatric ophthalmology and radiology. It must be differentiated from numerous simulating lesions. Accurate diagnosis by means of ultrasonography, CT, and MR is essential for prompt treatment and prevention of metastasis. The CT and MR findings in 45 patients are presented in this article in order to evaluate and compare the usefulness of these two imaging techniques in the diagnosis of retinoblastoma.
