Abstract

The signs of lower cranial nerve palsies are rare and are often caused by tumors. A 49-year-old woman was admitted to our hospital with progressive right-sided atrophy of the tongue, sternocleidomastoid and trapezius, dysarthria, and dysphagia for 3 years. Brain magnetic resonance imaging revealed a circular lesion adjacent to the lower cranial nerves. Cerebral angiography confirmed that the lesion was an unruptured aneurysm in the C1 segment of the right internal carotid artery. After endovascular treatment, the symptoms of this patient had partially improved.
