Purpose: We describe the characteristics of an isolated retinal cavernous hemangioma in a young female patient using multimodal imaging. Case description: Fundus examination of the right eye showed a large vascular mass, composed by clusters of dark red and dilated saccular angiomatous formations with superficial whitish fibroglial tissue and hemorrhages, located in the inferonasal peripheral retina, along the vascular arcade. On green-light fundus autofluorescence the lesion appeared hypoautofluorescent, with moderately hyperautofluorescent areas. On multiColor imaging it showed mainly a green pseudocolor, with knobby surface and well-defined irregular margins. Fundus fluorescein angiography showed early hypofluorescence within the tumor mass and late incomplete staining, without leakage. Ocular ultrasonography documented an elevated well-defined hyperechogenic lesion, with high internal reflectivity, without choroidal excavation, retinal detachment, or acoustic shadowing. Swept source optical coherence tomography showed multilobulated cavernous formations, varying in size, containing for the greatest part hyperreflective material, within an interconnecting fibrous scaffold and with an overlying partially adherent epiretinal membrane. Optical coherence tomography angiography documented a few highly reflective, tortuous and abnormal branching veins extending into the tumor mass, with a root-like appearance, and surrounding nodular changes, corresponding to the angiomatous formations. Conclusions: Different imaging modalities can be used in combination for a better evaluation of the pathological features of this rare vascular tumor.
