RESUMEN
BACKGROUND: Retropharyngeal calcific tendinitis is an aseptic inflammation of the longus cervicis muscle. This rare acute pain disorder of the neck region is a prognostically benign condition compared to neurological or otorhinolaryngological differential diagnoses. OBJECTIVE: To capture the clinical appearance, diagnostics, treatment and course of this rare disease. MATERIAL AND METHODS: In this retrospective monocentric observational study, demographic, clinical, paraclinical as well as treatment and follow-up data of all inpatients with a diagnosis of retropharyngeal calcific tendinitis admitted to the Diako Hospital Mannheim in the years 2018 to 2021 were analyzed. RESULTS: This study included four female and one male patient with an age between 36 years and 77 years. Severe neck pain with restriction of cervical spine rotation was the leading clinical appearance, in four out of five patients there was a painful swallowing disorder. Inflammatory markers were elevated in four patients. Characteristic MRI or CT imaging alterations of the cervical spine confirmed the diagnosis. The symptoms resolved within 4-14 days after treatment with nonsteroidal anti-inflammatory drugs (NSAID) and four patients additionally received glucocorticoids. No recurrences were observed during the follow-up period of 5-30 months. CONCLUSION: The good prognosis of this rare disease is reflected by the rapid remission of symptoms under NSAIDs and glucocorticoids and by the absence of recurrences during follow-up. CT or MRI imaging is required to rule out differential diagnoses, and to confirm the characteristic imaging alterations of retropharyngeal calcific tendinitis. Additionally, cerebrospinal fluid puncture and otorhinolaryngological assessment may be necessary in some cases.
