An infrequent cause of neck pain: Crowned dens syndrome

Abstract

In the usual clinical practice there is a growth in the demand for emergency services. Cervical pain is a very common pathology that concerns various health professionals. The crowned den syndrome is a very rare pathology, which is part of the spectrum of microcrystalline diseases of calcium pyrophosphate, causing a calcification of ligaments of the cervical odontoid process, leading to clinical signs of neck pain, fever and neck stiffness. This pathology enters into the differential diagnosis with potentially serious pathologies. In many cases it leads to unnecessary pharmacological procedures and expenses, mainly due to the ignorance that turns it into an infra diagnosed pathology.
