PURPOSE: To report an atypical case of a patient with symptomatic retinocytoma associated with diffuse calcified vitreous seeds. METHODS: Retrospective chart review. RESULTS: A 46-year-old healthy woman presented with a history of floaters in the right eye for several months. She had been referred for abnormal findings in the retina and vitreous on routine examination. Visual acuity was 20/20. An incidental retinocytoma associated with extensive calcified vitreous seeding was observed. Enhanced depth optical coherence tomography showed an absence of normal retinal layers with numerous cystoid cavities throughout the lesion. High-resolution 20-MHz posterior B-scan ultrasonography demonstrated that the calcified vitreous seeds emanated from the peaked portion of the retinal tumor. CONCLUSION: Calcified vitreous seeding is a rare finding associated with retinocytomas. Enhanced depth imaging optical coherence tomography and high-resolution B-scan ultrasonography may be useful tools in the diagnosis of this uncommon retinal tumor.
