The American journal of emergency medicine(2023)
Abstract
Crowned dens syndrome (CDS) occurs due to the deposition of calcium pyrophosphate (CPP) in the ligament tissue around the odontoid process of the axis. CDS is characterized by acute neck pain, stiffness, fever, and elevated inflammatory markers. It is a rare cause of neck pain among older people. We report a 71-year-old female patient who presented with acute neck pain, headache, with dizziness. Body temperature showed normal, with elevated C-reactive protein and ESR in the blood. Over the past 5 years, the patient has experienced neck and head pain several times.MRI of the head and CT scan of the neck showed calcification of the transverse atlantoaxial and cruciate ligament in combination with mild compression of the medulla oblongata. The patient was given non-steroidal anti-inflammatory drugs (NSAIDs) and colchicine for 10 days, with significant symptom improvement and no recurrence at 10 months of follow-up.
