CT scan may be helpful in the diagnosis of retinoblastoma.

On CT, retinoblastoma is characterized by enhancing intermediate-density soft-tissue mass or masses, with varying degrees of calcification.

+On CT, retinoblastoma is characterized by enhancing intermediate-density soft-tissue mass or masses, with varying degrees of calcification.
-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.
