Abstract

The clinical manifestations of crowned dens syndrome (CDS) include acute neck pain and neck stiffness accompanied by restricted cervical range of motion. CDS is frequently misdiagnosed as meningitis, epidural abscess, rheumatoid arthritis, rheumatoid polymyalgia, giant cell arteritis, cervical spondylosis or metastatic bone tumor, and the incidence of CDS appears to be underestimated. The present study reported on four cases of CDS diagnosed by CT. They included one male and three females, aged from 67 to 78 years, and their major symptoms were acute neck pain and restricted cervical range of motion. Serum C-reactive protein levels and erythrocyte sedimentation rate were significantly increased in all cases. Cervical CT scan revealed calcified deposits surrounding the odontoid process in all cases. Non-steroidal anti-inflammatory drugs (NSAIDs) markedly reduced the levels of inflammatory indicators and rapidly relieved the symptoms. CT scan is considered the gold standard for CDS diagnosis, which may demonstrate calcification around the odontoid process. The patients' symptoms may be improved by treatment with NSAIDs.
