A case of Crowned dens syndrome that manifested in the course of bronchitis

Abstract

    Eighty-four-year-old male had been suffering from fever, cough and phlegm followed by polyarthralgia was diagnosed as having a bronchitis, which subsided after administration of anti-biotics. However, fever and polyarthralgia including neck pain and elevated inflammatory blood parameters persisted. From cervical CT scan, he was thought to have been complicated by Crowned dens syndrome, a type of pseudo-gout occurred in the atlanto-axial joint. After he was administered with a non-steroidal anti-inflammatory drug, his symptoms gradually disappeared. From this case, it seems important to consider the relationship between pseudogout and various inflammatory diseases such as infection, malignancy, or rheumatic diseases.
