Abstract

A 10 month-old female visited our out-patient clinic, whose chief complaint was an enlargement of right eyeball since 5 month ago. Her physical examination disclosed Cafe-au-lait spots on abdomen and back and a tumor-like mass was seen on right vitreous cavity by slit lamp biomicroscopy, indirect ophthalmoscopy, and orbit CT. The working diagnosis was either neurofibromatosis or retinoblastoma, but choroidal hemangioma was also another possibility tomographically. However, MRI suggested the possibility of choroidal malignant melanoma unexpectedly. Subsequently the eye was enucleated and the tumor was confirmed to be a choroidal malignant melanoma. We report this interesting case and the other case of choroidal malignant melanoma diagnosed by MRI in 57 year-old male.
