Pseudo Uveal Melanoma Caused by Optic Disk Drusen With Juxtapapillary Choroidal Neovascular Membrane

Abstract

Purpose To describe two cases of choroidal hemorrhage caused by optic disc drusen-induced choroidal neovascularization simulating uveal melanoma Methods Observational case reports of two patients and brief review of the literature Results Two patients were referred with pigmented juxtapapillary lesions concerning for choroidal melanoma. Multimodal imaging revealed the presence of optic disc drusen with overlying choroidal neovascular membranes and peripapillary choroidal hemorrhage. Both patients were treated with antivascular endothelial growth factor and the lesions resolved. Conclusions In the setting of diagnostic uncertainty, careful multimodal imaging can assist in distinguishing between malignant choroidal melanoma and a benign simulating lesion. Optic disc drusen with associated neovascularization and hemorrhage should be included in the list of pseudomelanomas.
