Abstract

症例は,右頸部の疼痛と頸部伸展・回旋時の血圧低下を呈した71歳の男性である.頸部血管超音波検査では右内頸動脈に高度狭窄をみとめ,造影CTでは頸動脈球部周囲に造影効果をともなう軟部組織陰影がみられた.18F-FDG PET-CTでは同部に一致した高集積をみとめ,頸動脈痛(carotidynia)と診断した.約2週間で疼痛は消失し,右内頸動脈の狭窄も中等度まで改善,血圧低下は消失した.頸動脈の動脈硬化に,carotidyniaによる頸動脈洞の血管壁肥厚と血管周囲の炎症が加わることで,頸動脈過敏症を発症したと考えられた.<br>

A 71-year-old man presented with acute, right-sided neck pain and marked falls in blood pressure in response to cervical extension/rotation. Enhanced CT of the right carotid artery showed wall thickening and soft tissue enhancement surrounding the vessel. Ultrasonography demonstrated wall thickening and marked acceleration of the blood flow velocity. [<sup>18</sup>F] fluorodeoxyglucose (18F-FDG) positron-emission tomography (PET)-CT revealed increased FDG activity in the area of the right carotid bulb. The patient's symptoms resolved in 2 weeks with nonsteroidal anti-inflammatory drug; regression of wall thickening and decreased velocity were observed on follow-up ultrasonography. A carotid inflammatory process due to carotidynia in addition to atherosclerosis may increase carotid sinus baroreceptor stimulation, resulting in the onset of carotid sinus hypersensitivity.<br>
