Prevertebral calcific tendinitis results from calcium hydroxyapatite crystal deposits in the longus colli muscles, which induce symptoms similar to some surgically-treated conditions, such as retropharyngeal abscesses. Imaging techniques are critical for accurate diagnosis.
To describe the computed tomography (CT) findings associated with prevertebral calcific tendinitis.
Retrospective analysis performed in an 18-month period, searching for patients with neck CT and reports with diagnosis of "calcific longus collis tendinitis" or "prevertebral calcific tendinitis". CT images and clinical data available in the medical records were analyzed.
One hundred and thirty-four examinations were performed in the period studied. Nine patients who fulfilled inclusion criteria were identified and their CT imaging characteristics are presented. Six presented with calcific deposits in the right longus colli muscle. CT matched the clinical pain lateralization in all cases. Eight patients had no significant enhancement post injection of contrast media.
Prevertebral calcific tendinitis is a cause of acute cervical pain that clinically mimics a retropharyngeal abscess, however on neck CT has a characteristic appearance. Correct identification of this pathologic condition will help avoiding unnecessary invasive procedures.
椎体前钙化性肌腱炎是由羟基磷灰石晶体沉积于颈长肌所致，可引发与某些需手术治疗的疾病（如咽后脓肿）相似的症状。影像学技术对于准确诊断至关重要。
描述与椎体前钙化性肌腱炎相关的计算机断层扫描（CT）表现。
在18个月期间进行回顾性分析，查找接受颈部CT检查且报告诊断为“钙化性颈长肌腱炎”或“椎体前钙化性肌腱炎”的患者。对病历中可用的CT图像和临床资料进行分析。
在所研究期间共进行了134次检查。确定了9例符合纳入标准的患者，并展示了他们的CT影像学特征。6例患者右侧颈长肌出现钙化沉积。所有病例中CT表现均与临床疼痛的定位相符。8例患者注射造影剂后无明显强化。
椎体前钙化性肌腱炎是急性颈部疼痛的一个病因，临床上可模拟咽后脓肿，但在颈部CT上有特征性表现。正确识别这种病理状况有助于避免不必要的侵入性操作。
