61-years-old male patient presented with complain of neck swelling and soreness following contrast-enhanced (CE) CT examination with resolution of symptoms in 36-48 hours. He is diagnosed with hepatitis C virus and hepatocellular carcinoma (HCC); already treated with radiofrequency ablation for HCC. He had already undergone two CECT examinations before he was referred to our institution for disease staging/treatment. He also underwent three triphasic CT scan examinations at our institution during the course of treatment for treatment response and staging. Patient remained undiagnosed up to his fourth CT scan due to inability to relate symptoms with contrast administration. The patient was offered close monitoring on fifth CT exam and ultrasound of neck revealed enlarged and echogenic bilateral submandibular glands, however, thyroid and bilateral parotid glands appear unremarkable. This represents transient iodinated contrast induced sialadenitis with sparing of parotid glands.
一名61岁男性患者在增强CT检查后出现颈部肿胀和疼痛，症状在36 - 48小时内缓解。他被诊断为丙型肝炎病毒和肝细胞癌（HCC）；已接受HCC的射频消融治疗。在被转诊至我院进行疾病分期/治疗之前，他已经接受了两次CT增强检查。在治疗过程中，他还在我院接受了三次三相CT扫描检查，以评估治疗反应和进行分期。由于无法将症状与造影剂注射联系起来，该患者直至第四次CT扫描时仍未得到诊断。在第五次CT检查时对患者进行了密切监测，颈部超声显示双侧颌下腺肿大且回声增强，然而甲状腺和双侧腮腺未见异常。这代表了短暂性碘化造影剂诱发的涎腺炎，腮腺未受累。
