It was also noted on a few recent photographs. His pediatrician had checked the pupillary light reflex and indeed noted a dimmer and tan-colored reflex from the left pupil as opposed to a brighter and more reddish reflex in the left eye. She referred the child for further evaluation and management. Dilated fundus examination revealed a single large tumor in the left eye, occupying more than 50 percent of the globe. Ultrasonography showed a pattern consistent with calcifications within the tumor, and suggestive of retinoblastoma. A magnetic resonance imaging (MRI) scan showed no evidence of optic nerve or intracranial involvement. There were no other tumors in either eye. There was no family history of retinoblastoma. A decision was made to enucleate the eye because of the size of the tumor.
