A retinoblastoma with an unusual aspect in a 5-year-old girl

Abstract

A five-year-old girl presented with a white, semitransparent, slightly elevated retinal lesion in the left eye, with as most probable diagnosis retinoblastoma. Fluorescein angiography showed intraretinal vascular abnormalities and leakage. On computed tomography and ultrasound no calcifications were identified. As the tumor had grown, enucleation was performed and the diagnosis of retinoblastoma was confirmed by routine histology and by immunohistochemistry.
