Malignant arterial tumor emboli of sufficient size that is capable of causing organ infarction or ischemia are exceedingly rare. The majority of these emboli are associated with either primary or secondary pulmonary malignancies and commonly occur perioperatively or immediately postoperatively. This study describes an unusual case of acute lower extremity ischemia secondary to a malignant parotid tumor embolus with evidence of left ventricular involvement.
