Retinoblastoma and simulating lesions. Role of CT, MR imaging and use of Gd-DTPA contrast enhancement

Radiol Clin North Am. 1998 Nov;36(6):1101-17. doi: 10.1016/s0033-8389(05)70234-7.


The diagnosis of Rb can usually be made by clinical examination; however, patients should also be studied by CT and MR imaging to help determine the extent of the intraocular tumor, document intralesional calcification, confirm the diagnosis, and delineate orbital or intracranial involvement. These imaging techniques should aid the clinician in differentiating Rb from lesions that simulate Rb.
