Anomaly of internal carotid artery (ICA) is a very rare variation. In almost all the cases, the anomaly was on the right side. This right-sided predominance may be attributed to anatomical influences and factors affecting blood pressure.
A 67-years-old man presented to ear, nose and throat (ENT) outpatient clinic in Al Wakra Hospital complain of sore throat, there was associated medical co-morbidities (diabetic, hypertensive, hyperlipidemia and coronary artery diseases). ENT examination showed a pulsating, bulging mass on the right posterolateral oropharyngeal wall with normal mucosal covering. CT scan with contrast showed aberrant course of the right ICA which is coursing medially in prevertebral space and right posterolateral hypopharyngeal wall over a length of approximately 1.7 cm, making an acute U-turn before resuming the normal course and its distal aspects, only a thin layer of mucosa noted over the aberrant course of ICA.
Anomaly of ICA must be kept in mind in the evaluation of patients with sore throat associated with oropharyngeal mass especially in old-aged patients with atherosclerotic diseases.
颈内动脉（ICA）异常是一种非常罕见的变异。几乎在所有病例中，异常都发生在右侧。这种右侧优势可能归因于解剖学影响和影响血压的因素。
一名67岁男性到阿尔瓦克拉医院耳鼻喉科门诊就诊，主诉喉咙痛，同时伴有多种合并症（糖尿病、高血压、高脂血症和冠状动脉疾病）。耳鼻喉科检查显示右侧口咽后壁有一个搏动性、隆起的肿块，黏膜覆盖正常。增强CT扫描显示右侧ICA走行异常，在椎前间隙和右侧下咽后壁内侧走行约1.7厘米，在恢复正常走行及其远端之前形成一个急弯，在ICA异常走行上方仅可见一层薄黏膜。
在评估伴有口咽肿块的喉咙痛患者时，尤其是患有动脉粥样硬化疾病的老年患者，必须考虑到ICA异常。
