Differential diagnoses of inflammatory hip joint

Abstract

The differential diagnoses of inflammatory hip diseases play an important role for the diagnosis of hip pain. The radiological manifestations of rheumatic inflammatory hip pain with the corresponding use of imaging modalities were dealt in part 1 of the CME article. In this second part a systematic approach is explained in order to differentiate the many rheumatic diseaeses from degeneration, synovial tumors and infections. The interpretation of the pathologies seen in imaging in association with the clinical phenotype is more precisely elucidated for the individual differential diagnoses. The concomitant occurrence of different diseases, sometimes as secondary complications, has a substantial influence on treatment planning and should be recognized by radiologists.
