Presentation
Left eye leucocoria.
Patient Data
A well defined hyperechoic posterior chamber retinal based mass with macrocalcification within the retina. Thin rim of subretinal fluid which is hypoechoic compared to the vitreous suggestive of an exudative retinal detachment.
CT findings correlate with ultrasound with no evident extra ocular spread. No contralateral eye involvement.
Case Discussion
Retinoblastomas are the most common childhood neoplasms of the eye. It presents with white eye reflex and CT identifies lesional calcification to favor the diagnosis. They are often associated with retinal detachment (exudative). They may remain confined to the globe or spread outwards into the optic nerve, orbital apex and even meninges. No spread identified in this case.
