B-scan ultrasonography of an eye with choroidal melanoma before treatment with plaque brachytherapy with PPV, trans-vitreal biopsy, silicone oil insertion, and prior to ocular tumor lysis (a, L2) and 13 months later when ocular tumor lysis occurred (b, T2PE). Prior to plaque brachytherapy and tumor lysis, the tumor exhibited a collar-button configuration and adjacent inferonasal subretinal fluid. Ocular tumor lysis presented as a fibrinous membrane on the anterior lens surface and pigment dispersed on the posterior lens surface, posterior synechiae, extensive pigment in the vitreous, pigment dispersed throughout the surface of the retina and subretinal space, pre-retinal cellular membranes, tumor necrosis, and an inferonasal rhegmatogenous retinal detachment from an atrophic retinal hole overlying the tumor.
