[Acute calcific prevertebral tendinitis: case report and literature review].

Prevertebral calcific tendinitis is an uncommon cause of acute neck pain characterized by the identification of calcifications at C1-C2 level and the presence of a liquid collection at the prevertebral space which causes the displacement of the prevertebral radiographic line in imaging studies. It is very important to identify this rare, benign and self-limiting pathology, in order not to confuse it with other diseases that could erroneously lead to inappropriate treatment.
