Abstract:
:We review our experience with unusual ocular pathologies, some mimicking retinoblastoma, that were referred to our institution during the past two decades. After presenting the imaging anatomy of the normal eye, we discuss pertinent clinical and pathological features, and illustrate the US and MRI appearance of retinoblastoma, medulloepithelioma, uveal melanoma, persistent fetal vasculature, Coats disease, corneal dermoid, retinal dysplasia and toxocara granuloma. Features useful in discriminating among these entities are emphasized.
