Longus Colli Tendinitis in a Patient Presenting with Neck Pain and Acute Systemic Inflammation

The diagnosis of longus colli tendinitis (LCT) is sometimes challenging, especially when laboratory data show marked inflammation and neuroimaging studies do not indicate calcification within the tendon of the longus colli muscles. We herein report a case of LCT that presented with elevated inflammation parameters without calcification on imaging. Findings characteristic of LCT, such as prevertebral hyperintensity areas on T2-weighted images and no signs of purulent diseases, informed our diagnosis of LCT. Enhanced computed tomography and magnetic resonance imaging are useful procedures when diagnosing LCT after ruling out other critical purulent diseases.
