Asian Spine J. 2010 Dec;4(2):123-7. doi: 10.4184/asj.2010.4.2.123. Epub 2010 Nov 24.


Acute calcific prevertebral tendinitis, which is also known as retropharyngeal calcific tendinitis and longus colli tendinitis, is an under-recognized cause of acute cervical pain produced by an inflammation of the longus colli muscle. The typical characteristics of this entity are calcifications at the superior insertion of the longus colli tendons at the C1-C2 level and fluid collection in the retropharyngeal space. The differential diagnosis includes a retropharyngeal abscess, infectious spondylitis or traumatic injury. Knowledge of the clinical and imaging findings can prevent a misdiagnosis and inappropriate attempts at surgical drainage.
