Differentiation of true from mimicking Eagle’s syndrome based on conventional radiography is difficult; however, cone beam computed tomography (CBCT) images can contribute to proper diagnosis of mimicking Eagle’s syndrome. The aim was to study radiological images of a 37-year old female patient (patient #1), with chronic cervicofacial pain who underwent radiological diagnosis with a conventional panoramic machine; another 75-year old male patient (patient #2), with chronic oropharyngeal pain, underwent a radiological diagnosis with the CBCT machine, with a field of a view of 16 × 12 cm. Exposure factors were 120 kVp, 7 mA, with a 20 s exposure time of acquisition. The results show a panoramic image (patient #1) with a pathologically elongated styloid process 46 mm of length, which was surgically removed, releasing the patient from further pain episodes. CBCT acquisition (patient #2) showed an impacted left maxillary canine in the edentulous maxilla and a peculiar elongation of both stylohyoid complexes as impressive, “collar-like”, bilateral, elongated, multiple segmented, calcified stylohyoid complexes, without pressure on the vital neurovascular neck structures, mimicking true Eagle’s syndrome. The impacted maxillary canine was surgically extracted with a subsequent resolution of pain episodes and the cessation of neurological complaints. The conclusions suggest that the use of CBCT images can contribute to differentiating mimicking from true Eagle’s syndrome, which has been rarely reported in the literature.

锥形束CT（CBCT）在区分真人与模仿鹰氏综合症中的应用。

基于传统的放射线照相很难区分真假与模仿鹰氏综合症。但是，锥形束计算机断层扫描（CBCT）图像可有助于正确诊断模仿Eagle综合征。目的是研究一名37岁女性（患有慢性宫颈口痛）的女性患者的放射线图像，该患者使用传统的全景机器进行了放射学诊断。另一位患有慢性口咽痛的75岁男性患者（2号患者）使用CBCT机器进行了放射学诊断，视野为16×12 cm。曝光因子为120 kVp，7 mA，采集时间为20 s。结果显示一幅全景图（患者＃1），其病理伸长的茎突长度为46毫米，已通过手术将其切除，使患者免于进一步的疼痛发作。CBCT采集（2号患者）显示，上颌无牙的上颌尖牙受累，两个类突舌肌复合体都有奇特的伸长，表现为令人印象深刻的“领状”，双侧，细长，多节段，钙化的类突舌肌复合体，对生命体没有压力神经血管颈部结构，模仿真正的鹰氏综合症。通过手术拔出患上颌犬，随后缓解疼痛发作和停止神经系统不适。结论表明，使用CBCT图像可有助于区分模仿与真正的Eagle综合征，这在文献中鲜有报道。CBCT采集（2号患者）显示，上颌无牙的上颌尖牙受累，两个类突舌肌复合体都有奇特的伸长，表现为令人印象深刻的“领状”，双侧，细长，多节段，钙化的类突舌肌复合体，对生命体没有压力神经血管颈部结构，模仿真正的鹰氏综合症。通过手术拔出患上颌犬，随后缓解疼痛发作和停止神经系统不适。结论表明，使用CBCT图像可有助于区分模仿与真正的Eagle综合征，这在文献中鲜有报道。CBCT采集（2号患者）显示，上颌无牙的上颌尖牙受累，两个类突舌肌复合体都有特殊的伸长，表现为令人印象深刻的“领状”，双侧，拉长，多节段，钙化的类突舌肌复合体，而对生命至关重要神经血管颈部结构，模仿真正的鹰氏综合症。通过手术拔出患上颌犬，随后缓解疼痛发作和停止神经系统不适。结论表明，使用CBCT图像可有助于区分模仿与真正的Eagle综合征，这在文献中鲜有报道。模仿真正的鹰氏综合症。通过手术拔出患上颌犬，随后缓解疼痛发作和停止神经系统不适。结论表明，使用CBCT图像可有助于区分模仿与真正的Eagle综合征，这在文献中鲜有报道。模仿真正的鹰氏综合症。通过手术拔出患上颌犬，随后缓解疼痛发作并停止神经系统不适。结论表明，使用CBCT图像可有助于区分模仿与真正的Eagle综合征，这在文献中鲜有报道。
