Calcific cerebral embolus from calcific carotid stenosis
We experienced a case of calcific cerebral embolus originated from calcific stenosis of the left internal carotid artery. A 64-year-old female presented with the right arm mild hypesthesia and weakness. Computed tomogram (CT) of the head and magnetic resonance imaging (MRI) demonstrated a hemorrhagic infarction in contact with spotty calcification on the left parietal lobe surface. A carotid angiogram disclosed approximately 50% stenosis of the left internal carotid artery (ICA), and a three-dimensional CT (3DCT) angiogram with a multiplanar reconstruction (MPR) image revealed calcification at the stenosis. No other cause for the calcific embolus other than the calcific carotid stenosis could be found. Calcific cerebral emboli are uncommon, and a case originated from calcific carotid stenosis is extremely rare.
