[Rare cause of acute neck pain]

The acute calcific tendinitis of the longus colli muscle is a rare inflammatory process of the prevertebral muscles. The clinical picture includes acute neck pain, limited range of motion of the cervical spine with stiffness and odynophagia. The laboratory findings demonstrate inflammatory signs. The incidence of the disease peaks between the third and sixth decade. The knowledge of the characteristic radiologic findings and the self-limiting course prevents the patient from needless medical and surgical interventions.
