ABSTRACT
Objective To explore the manifestation and diagnostic value of CT in retinoblastoma. Methods Twentythree cases of retinoblastomas proven by operation and pathologic examination were collected. Their CT images, clinical symptoms and pathologic results were retrospectively analyzed. Results Twentythree patients of retinoblastomas aged from 4 months to 9 years (mean 2.4 years). CT images showed soft tissue mass (shaped as node, crescentshaped or occupied the entire space of the eyeball) was in the globe of all cases. There was calcification in 19 cases (82.6%), including “small pinch” in 12 cases or “patches” in 7 cases. Five cases were found the optic nerve thickened (21.7%), and 1 case of intracranial invasion through the optic nerve canal (1/23), and 6 cases of retina detachment (6/23). The lesion showed mild or moderate enhancement after intravenous contrast medium were performed. Conclusion CT has an advantage on showing the size, shapes, intrastructures and invasive degree of the lesion, and is meaningful to the diagnosis and differential diagnosis of retinoblastoma.
