Abstract
We present a unique case of crowned dens syndrome (CDS) that developed after endoscopic retrograde cholangiopancreatography (ERCP) in a patient who presented with fever and neck pain. Administration of non-steroidal anti-inflammatory drugs was extremely effective for relieving fever and neck pain, and in the improvement of inflammatory markers. To the best of our knowledge, this is the first case report of CDS caused by an ERCP procedure. In a patient with fever and neck pain after an ERCP procedure, CDS should be considered in the differential diagnosis.
Core tip: There are numerous differential diagnoses for patients with fever after an endoscopic retrograde cholangiopancreatography (ERCP). A careful evaluation of medical history and a physical examination provide clues to making a definitive diagnosis. Retrograde cholangitis is a well-known complication of ERCP; additionally, pseudogout is known to develop after severe illnesses or surgery. This case report describes a patient with pseudogout of the neck, which is also known as crowned dens syndrome (CDS). CDS should be considered in a patient with fever and neck pain after an ERCP procedure.
