The thickening of flexor tendons pulleys: a useful ultrasonographical sign in the diagnosis of psoriatic arthritis

Its specificity and positive predictive value are not very high; however, if it is included in a complete classification process, sonographers should report it during hand evaluations of patients with arthritis.
