茎状突起による両側内頸静脈狭窄例

抄録

A 34-year-old man consulted a neurosurgeon for severe headache. A CT angiography showed constrictions of the internal jugular vein on either side. The surgeon placed stents in the internal jugular veins of both sides, and the patient reported alleviation of the headaches after the surgery. However, a follow-up CT showed that the stents had become crushed between the styloid processes and the C1 lateral processes on both sides. Therefore, we resected the styloid processes on both sides to avoid recurrent obstruction, and the patient had no more headaches. In recent years, there have been reports of various styloidogenic diseases that cannot be considered as classic cases of Eagle syndrome. We believe that it is necessary to establish a new disease concept, including this case as a case with a new variant of Eagle syndrome.
