Amaurosis fugax due to pleomorphic sarcoma in the left atrium

This report describes a case of amaurosis fugax due to a rare primary cardiac sarcoma.

A patient who was recently diagnosed with left atrial pleomorphic sarcoma presented with a chief complaint of multiple episodes of intermittent vision loss in the right eye during the course of radiation therapy.

The authors postulate emboli from the left atrial sarcoma entered systemic circulation and subsequently caused brief episodes of transient occlusion to retinal, ophthalmic and/or ciliary arteries leading to momentary retinal hypoxia. We believe this is a novel finding, previously unreported in the literature, of transient embolic occlusion without permanent visual sequelae due to a malignant primary cardiac pleomorphic sarcoma.
