The objective of this study was to characterize cervical computed tomography (CT) findings in Kawasaki disease (KD) patients that may facilitate early diagnosis.
We retrospectively reviewed cervical CT images of 78 children with cervical lymphadenopathy to analyze the distribution and morphology of lymphadenopathy and other soft-tissue findings.
Twenty-eight patients were diagnosed with KD. Fifty had other diseases (non-KD). Retropharyngeal edema was observed in 82% (23/28) of KD and 30% (15/50) of non-KD (P < 0.01) cases. Retropharyngeal lymphadenopathy was observed in 89% (25/28) of KD and 48% (24/50) of non-KD (P < 0.01) cases. Levels III and IV lymphadenopathy was found in only 1 KD case, whereas levels III and IV lymphadenopathy was found in 58% (29/50) (P < 0.01) and 36% (18/50) (P < 0.01) of non-KD cases, respectively.
Retropharyngeal lymphadenopathy and retropharyngeal edema are relatively common features of KD on CT. Given the potentially serious complications of KD, this diagnosis is an important consideration in a young child presenting with these imaging findings.
本研究的目的是描述川崎病（KD）患者的颈部计算机断层扫描（CT）表现，以促进早期诊断。
我们回顾性分析了78例有颈部淋巴结病的儿童的颈部CT图像，以分析淋巴结病的分布和形态以及其他软组织表现。
28例患者被诊断为KD。50例患有其他疾病（非KD）。82%（23/28）的KD患者和30%（15/50）的非KD患者出现咽后水肿（P<0.01）。89%（25/28）的KD患者和48%（24/50）的非KD患者出现咽后淋巴结病（P<0.01）。仅1例KD患者发现Ⅲ级和Ⅳ级淋巴结病，而非KD患者中分别有58%（29/50）（P<0.01）和36%（18/50）（P<0.01）发现Ⅲ级和Ⅳ级淋巴结病。
咽后淋巴结病和咽后水肿是KD患者CT检查中相对常见的特征。鉴于KD可能引发严重并发症，对于出现这些影像学表现的幼儿，这一诊断是重要的考虑因素。
