Choroidal hemorrhage simulating choroidal melanoma

摘要

Posterior uveal melanoma generally manifests features of an elevated, pigmented (85%), dome-shaped (75%), choroidal mass (90%) with subretinal fluid (71%). The differential diagnosis includes numerous conditions of retinal origin, retinal pigment epithelial origin, and choroidal origin. In a study of 1,739 pseudomelanomas, the 3 most common conditions included choroidal nevus (49%), peripheral exudative hemorrhagic chorioretinopathy (8%), and congenital hypertrophy of the retinal pigment epithelium (6%).3 In that series, choroidal hemorrhage represented only 2% of all pseudomelanomas.
