Ocular toxocariasis studied by CT scanning.

Ocular Toxocara canis infection causing larval granulomatosis and leading to chronic endophthalmitis and retinal detachment is a well-defined cause of unilateral leukokoria in children. The computed tomographic (CT) scan revealed a diffuse, nonenhancing, well-defined hyperdense lesion occupying most of the globe. The CT findings do not definitively differentiate the diffuse endophthalmitis of larval granulomatosis from retinoblastoma or other pseudogliomas.
