Uveal melanoma and similar lesions: the role of magnetic resonance imaging and computed tomography.
The uvea provides a suitable substrate for tumor cells because it is the most vascular portion of the eye. Most primary and metastatic ocular neoplasms involve the choroid, with the most common being malignant melanoma. We review the features of uveal melanomas seen on MRI and CT images and evaluate certain neoplastic and non-neoplastic intraocular lesions that may simulate uveal melanomas.
