Case Discussion
Choroidal melanomas, also called malignant uveal melanomas, are the most common primary ocular tumor in adults.
On imaging, melanomas appear hyperdense on CT scan and hyperintense on T1WI on MRI. Mild enhancement can be seen on post-contrast images.
Choroidal melanomas can be associated with retinal detachment on presentation. Systemic metastasis may occur in the liver, lung, bone, kidney and brain.
