石灰沈着性頸長筋腱炎の3例

Three cases report of calcific retropharyngeal tendinitis

Ⅰ　はじめに

　石灰沈着性頸長筋腱炎は，頸長筋腱への石灰沈着による急性炎症であり，急激に頸部痛，嚥下痛，頸部の可動制限をきたすが，その予後は良好で，通常1，2週間で自然軽快する。しかし，症状，局所所見が類似する咽後膿瘍との鑑別がしばしば問題となる。今回われわれは石灰沈着性頸長筋腱炎の3例を経験したので若干の文献的考察を加えて報告する。

　Calcific retropharyngeal tendinitis is an inflammatory process of the superior oblipue tendons of the longus colli muscle caused by deposition of calcium hydroxyapatite. The clinical findings include neck pain and pain on swallowing,limitaions of neck movement. This condition may be misdiagnosed as retropharyngeal abscess. The diagnosis can be established radiogaraphically by identification of pathognomonic findings of calcifications in front of the C1-2 cervical spine. Knowledge of the clinical and imaging findings can prevent a misdiagnosis and inappropriate attempts at surgical drainage.
