  • Abstract
  • Look Inside

A 50-year-old male presented with blurring in his left eye since 5 months before. He had received gas-trectomy for stomach cancer 6 years before. His corrected visual acuity was 0.7 left. A dome-shaped yellowish-white tumor was present in the posterior fundus. Ultrasonography and magnetic resonance imaging were suggestive of meta-static choroidal tumor. Following radiotherapy, his visual acuity deteriorated to 0.01 3 months later. The dome-shaped tu mor had increased in size to assume mushroom-like appearance. 123I-IMP single photon emission CT (SPECT) showed an intense accumulation in the whole left eye 24 hours after injection. The left eye was enucleated and was di-agnosed with choroidal malignant melanoma. This case illustrates that 123I-IMP SPECT may be useful in the diagnosis of choroidal malignant melanoma.
