Abstract

Aim: To study the diagnostic value of MRI for the detection of scleral infiltration and extrascleral extension of uveal melanoma. Materials and Methods: Twelve consecutive patients with clinically suspected large uveal melanoma were examined by MRI. All of the patients underwent enucleation or exenteration. The clinical and histopathological findings were compared. Results: The clinical diagnosis of uveal malignant melanoma was confirmed by histology in each case. MRI allowed detection of scleral infiltration with a sensitivity of 100% and a specificity of 50%. For extrascleral extension, MRI had a sensitivity of 100% and specificity of 89%. Conclusions: Using fat suppression technique and enhancement with contrast medium, MRI proved to be a valuable ancillary method for the assessment of scleral infiltration and extrascleral extension.
