On CT, retinoblastoma is characterized by enhancing intermediate-density soft-tissue mass or masses, with varying degrees of calcification.[1] CT detects intraocular, extraocular, and intracranial disease extension, is very good at delineation of bony abnormalities and readily depicts tumoral calcifications with a sensitivity greater than 90%. However, delineation of intraocular soft tissue detail is limited and the sensitivity of CT to detect optic nerve invasion is very low even in patients with extensive optic nerve invasion.
