Calcific longus colli tendinitis is an inflammatory lesion in the prevertebral space. When prevertebral effusion is observed on MRI, awareness of the prevertebral muscle swelling with signal change and the associated mass effect would suggest that the main site of the lesion is the prevertebral space, not the retropharyngeal space and may thus prevent both misdiagnosis as a retropharyngeal abscess and unnecessary treatment. The variability in the level of calcification and prevertebral effusion is highlighted in the present study in order to assist in the establishment of the correct radiological diagnosis.
