Abstract
Orbital infarction syndrome (OIS) is a disease of rare occurrence owing to the rich
orbital vascular anastomotic network. We describe a case of a middle-aged female who
presented with an acute left middle cerebral artery (MCA) territory infarct with left
terminal internal carotid artery and MCA occlusion, underwent emergency mechanical
thrombectomy, and developed painful loss of vision shortly after diagnosed as OIS
based on clinical and radiological findings. The rarity and severity of OIS, especially
in the setting of mechanical thrombectomy, warrant radiologists to be aware of this
entity to ensure preventive measures or aid in prompt diagnosis to institute timely
treatment.
