Multimodal imaging of a case of retinal cavernous hemangioma.

Abstract

Herein, we reported a case of retinal cavernous hemangioma (RCH) and its multimodal imaging. Many grape-like lesions were incidentally found along the distal portion of the vascular arcade in a 23-year-old man's superonasal quadrant of the retina. The best-corrected visual acuity was 20/20 in both eyes. The fluorescein angiography showed saccular lesions that slowly filled with hypofluorescence in the early stage and clusters of aneurysms with hyperfluorescence and a special "fluorescein cap" appearance in the late stage. The optical coherence tomography angiography (OCTA) B-scan revealed multilocular cavernous spaces with different sizes in the inner retinal layers, varying signals, and an epiretinal membrane. The enface OCTA of retina showed grape-like changes and multiple highly reflective signal cavities with clear and complete boundaries. Different multimodal images are better for understanding the characteristics of RCH and more convenient for its diagnosis and follow-up.
