Abstract
Retinoma or retinocytoma is a spontaneously arrested or spontaneously regressed variant of retinoblastoma. With the advent of the latest non-invasive imaging techniques, it is possible to evaluate the microstructural and microvascular changes associated with this tumour. Although there are a few reports which describe the imaging findings in retinocytoma, information regarding retinocytoma on the multicolour imaging is lacking. Here, we describe the multimodal imaging features in a patient with classic features of retinocytoma with special emphasis on its multicolour imaging features.

Abstract
Retinoblastoma (RB) is a malignant intraocular tumor that frequently occurs in infants and toddlers. Although the most of RB patients in the developed countries could survival from this cancer, the patients in undeveloped areas are still suffering. The human retinal pigment epithelial cell line ARPE-19 and human retinoblastoma (RB) cell lines HXO-RB44, Y79, and WERI-Rb1 were cultured. The mRNA levels of BANCR and miR-204-3p in these cell lines were measured by qRT-PCR. After transfection with sh-BANCR or treatment with miR-204-3p inhibitor in Y79 cells, the cell proliferation rate, growth, invasion, migration, apoptosis and Wnt/β-catenin signaling pathway activity were measured. The regular Y79 and Y79 cells stably expressed sh-BANCR were injected subcutaneously into nude mice, respectively. The volumes and pathohistological futures of tumors were compared. The biochemical features similar to the cell culture were detected and compered. The mRNA measurements showed that BANCR negatively modulate miR-204-3p expression via directly integration with it. Besides, miR-204-3p and Wnt/β-catenin signalling pathway were found to participate in the oncogenic effects of BANCR on RB cell line by Hoechst staining, cell Counting Kit-8 (CCK-8) assay, wound healing assay, transwell assay, and Western blot analysis in vitro. In addition, an in vivo tumorigenesis experiment in nude mice injected with Y79 cells stably expressed sh-BANCR conformed in the effects of BANCR on RB. Taken together, the knockdown of BANCR inhibited cell proliferation, apoptosis, invasion, and migration in RB via targeting miR-204-3p, the mechanism may involve inhibiting Wnt/β-catenin signaling pathway.
