We reported 2 patients with pseudogout manifested by severe posterior neck pain. Patient 1 was a 78-year-old woman. She had experienced attacks of posterior neck pain several times for 4 years. On July 3, 2001, she developed severe pain in the posterior neck and left acromioclavicular joint, and was admitted to our hospital. On examination, her body temperature was 38.1° C, ESR 140 mm/hr and CRP 14.7 mg/dl. Linear calcifications in meniscus of the right knee and left acromioclavicular joint were observed in roentgenograms. The CT of the cervical spines revealed multiple nodular calcifications in the ligamenta flava at the level of C3-C7. She was treated with NSAIDs, and her symptoms and inflammatory reactions rapidly subsided. Patient 2 was was a 76-year-old man. His clinical courses and laboratory findings were very similar to those of patient 1. Both patients presented here were older than 70, and shared such common clinical findings as back neck pain, fever, elevations of serum ESR and CRP level, and effiveness of NSAIDs. We could not detect any findings that could explain the neck pain and fever in cervical spinal roentgenograms and MRIs. Cerebrospinal fluid examinations showed no abnormalities. We diagnosed them as having cervical arthritis caused by calcium pyrophosphate dihydrate deposition (pseudogout) based on the cervical CT examinations, which showed multiple nodular calcifications in the ligamenta flava. Calcium pyrophosphate dihydrate deposition on cervical spine is very rare, and only 50 patients with this condition have been reported to date. In the literatures, the mean age of patients with cervical spine pseudogout is old (72.3 years old) and 84% of them are females. The ligamenta flava at the level of C3-C6 and transverse ligament of the atlas are most commonly involved. Pseudogout of the cervical spine should be considered as a differential diagnosis when we examine the elderly patients with back neck pain. Cervical spinal CT is the most sensitive and useful examination to diagnose this disease.
