ASENSIO SANCHEZ, VM; ALONSO, M  e  SIERRA, JM. Positron emission tomography in the diagnosis of orbital relapse of choroidal melanoma. Arch Soc Esp Oftalmol [online]. 2005, vol.80, n.2, pp.113-115. ISSN 0365-6691.

Case report: A 72-year-old man with a large choroidal melanoma was treated with enucleation. Three years later MRI demonstrated images compatibles with recurrent tumor in the orbit. PET studies showed no focal hypermetabolic abnormalities. Discussion: In patients after enucleation of choroidal melanoma, conventional imaging techniques can fail to establish differentiation between malignant from post-surgery and benign anatomic abnormalities in orbital tissue that can be detected by PET scanning.
