Retrobulbar metastasis of breast primary- Once in a blue moon lesion

Breast cancer is the most common cancer in females and mostly metastasizes to liver, brain, bones, and lungs. It only rarely involves the choroid; signs of choroidal metastases become apparent late in the course of disease and are therefore linked to bad prognosis. These signs are often ignored as benign symptoms. Although many features may overlap with benign orbital diseases, MRI remains the modality of choice to help differentiate it from others. We present a case of a female patient who presented with visual impairment with unusual imaging features of retrobulbar choroidal metastases from primary breast cancer.
