Calcific retropharyngeal tendinitis/retropharyngeal calcific tendinitis is an inflammation of the longus colli muscle caused by calcium hydroxyapatite crystal depositon in the longus colli muscle tendon. The three major symptoms are neck pain, limitations of neck movement, and swallowing pain. We treated 8 cases of calcific retropharyngeal tendinitis/ retropharyngeal calcific tendinitis. Each patient complained of neck pain, limitations of neck movement, and swallowing pain. The only local finding was the smooth swelling of the posterior pharyngeal wall. CT imaging showed calcification of the tendon of the longus colli muscle and a low density area in the retropharyngeal space without ring enhancement, suggesting a retropharyngeal abscess. MR imaging showed the smooth swelling of the retropharyngeal space and an increased signal intensity on T2-weighted MR imaging. Calcific retropharyngeal tendinitis heals spontaneously, and treatment is not usually required. However, the clinical outcomes are similar and can be confused with retropharyngeal abscess and pyogenic spondylitis, so antibiotics are administrated in many cases. In our report, 7 patients were hospitalized and were treated with the intravenous administration of antibiotics, while 1 patient who refused hospitalization was treated with an oral antibiotic. Steroids were administrated in 2 cases. The 7 patients who were hospitalized were cured within 6 to 10 days.
