Acute calcific retropharyngeal tendinitis or longus colli tendinitis is an uncommon benign condition presenting as acute neck pain. Clinically, it can be misdiagnosed as retropharyngeal abscess, traumatic injury, or infectious spondylitis. The diagnosis is made radiographically by calcification anterior to C1-C2 and prevertebral soft-tissue swelling. We present two cases of this uncommon condition to illustrate the classic findings on CT and MRI. In addition to the typical calcifications anterior to C1-C2, we detected a retropharyngeal effusion in both patients and effusions involving both lateral atlantoaxial joints in one patient, which to our knowledge has not been published in the literature. In both patients, the correct diagnosis was established by prospective review of the radiographic studies. Recognition of the pathognomonic imaging appearance allows for easy diagnosis preventing unnecessary tests and treatment.
急性钙化性咽后肌腱炎或颈长肌肌腱炎是一种罕见的良性疾病，表现为急性颈部疼痛。临床上，它可能被误诊为咽后脓肿、创伤性损伤或感染性脊柱炎。通过C1 - C2前方的钙化和椎前软组织肿胀进行影像学诊断。我们报告两例这种罕见疾病，以说明CT和MRI上的典型表现。除了C1 - C2前方典型的钙化外，我们在两名患者中均检测到咽后积液，在一名患者中还检测到累及双侧寰枢外侧关节的积液，据我们所知，这在文献中尚未见报道。在两名患者中，通过对影像学研究的前瞻性回顾确立了正确诊断。认识到特征性的影像学表现有助于轻松诊断，避免不必要的检查和治疗。
