Three-Dimensional Reconstruction CT in Diagnosis of Eagle's Syndrome: A Retrospective Study
以立體重組電腦斷層影像診斷Eagle氏症候群：回顧性研究
摘要
Eagle氏症候群是指較長的莖突或是鈣化的莖突舌骨韌帶，造成轉頭時頸部疼痛或吞嚥時喉嚨痛等症狀。本研究的目的在探討以立體重組電腦斷層影像診斷Eagle氏症候群是否有效且可靠。在過去兩年中，十九位臨床上懷疑Eagle氏症候群的患者接受了電腦斷層檢查。我們使用多排探頭電腦斷層，並重組出橫切面、冠狀切面、以及立體重組影像。兩位放射科醫師分別在有及沒有立體重組影像的情況下，判讀了所有檢查的影像，然後我們比較報告的莖突長度及測量莖突長度所需的時間。九位患者有十一個較長的莖突或是鈣化的莖突舌骨韌帶。不論有沒有立體重組影像可以判讀，兩位放射科醫師對Eagle氏症候群的診斷沒有差異。如果有立體重組影像，判讀所需的時間可以顯著的減少。在切面影像和立體重組影像之間有顯著的相關。當臨床上懷疑Eagle氏症候群時，立體重組電腦斷層是有效且可靠的影像診斷工具。

Eagle's syndrome is defined as symptoms such as neck pain on turning head and pain on swallowing, caused by elongated styloid process or calcified stylohyoid ligament. The purpose of this study is to investigate the effectiveness and reliability of three-dimensional (3D) reconstruction CT to make diagnosis of Eagle's syndrome. Nineteen patients with clinical suspicion of Eagle's syndrome underwent CT study in the past 2 years. A multidetector CT (MDCT) scanner was used for data acquisition, and then axial, coronal and 3D image reconstruction was performed. Two radiologists reviewed all the studies, including images with and without 3D reconstruction. The lengths of the styloid processes and the time interval for the readers to report the length of the styloid processes were compared. Nine patients with 11 elongated styloid processes or calcified stylohyoid ligaments (3.87±0.46cm) were all recognized by the two radiologists with almost perfect interobserver agreement, regardless of 3D images available or not. The interpretation time was significantly less if 3D reconstruction images were available for the readers (p＜0.001). There is significant correlation between the styloid process lengths measured on sectional images and on 3D CT. In conclusion, for patients with clinically suspicious Eagle's syndrome, 3D CT is an effective and reliable imaging tool for the radiologists to make a diagnosis.
