Well defined sharply marginated fungating soft tissue lesion arising from the uveal coating of the superior quadrant of the left eye globe. It displays bright signal on T1, low signal on T2 with avid enhancement on post contrast study. No extra ocular extension and with clear retro orbital fat.

Ocular ultrasound reveals a well defined soft tissue choroidal mass with moderate echogenicity and internal vascularity.
Case Discussion
MRI signal intensities are characteristic of primary uveal melanoma. US with Doppler integration show the characteristic mushroom shape fungating mass with internal vascularity.
