Abstract

Background: Acute Calcific Tendinitis of the Longus Colli (ACTLC), also known as Retropharyngeal Calcific Tendinitis
(RCT), is a rare, benign aseptic inflammatory condition caused by the deposition of calcium hydroxyapatite. Because its clinical presentation is characterized by the classic triad of acute neck pain, odynophagia, and restricted neck movement, this condition is easily misdiagnosed as dangerous deep neck infections, particularly retropharyngeal abscess.
Objective: To describe the clinical and imaging features of a case of acute calcific tendinitis of the longus colli and to
emphasize the distinguishing findings that help differentiate it from retropharyngeal abscess and guide effective conservative management.
Subjects and Methods: This case report was conducted in accordance with the CARE guidelines. Data were collected from a 41-year-old female patient admitted with acute neck pain syndrome, based on medical records, laboratory investigations, magnetic resonance imaging (MRI), cervical spine radiography, treatment with nonsteroidal anti-inflammatory drugs (NSAIDs), and follow-up
of the clinical course.
Results: MRI and cervical spine radiography revealed the characteristic calcific deposit at the anteroinferior aspect of the C1-C2 vertebrae (the insertion site of the longus colli tendon), accompanied by retropharyngeal fluid collection and diffuse edema extending from C2 to C4. Important negative findings included the absence of a localized abscess cavity, the absence of rim enhancement, and
the absence of free gas within the soft tissues. The patient responded rapidly to conservative anti-inflammatory therapy with Naproxen combined with analgesics; symptoms improved markedly within a few hours, with complete clinical recovery after 5 days.
Conclusion: Accurate recognition of ACTLC based on the presence of prevertebral calcification at C1-C2 and non-suppurative retropharyngeal edema is the key to enabling clinicians and radiologists to implement appropriate conservative management and avoid overtreatment.
