A 35-year-old woman experienced sudden onset of right-sided weakness due to a left middle cerebral artery stroke 12 hours after she had obtained a love bite on the left side of her neck. Duplex ultrasonography showed a near-occlusion of the left internal carotid artery (ICA) and CT angiography revealed a mural thrombus at the same location. This case report shows that love bites on the neck are a rare cause of embolic stroke. The most likely aetiology is embolization of thrombus material from a local intimal lesion of the ICA.
