Core Tip
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.
