| Abstract |
| Abstract The aim was to evaluate synovial proliferation
ultrasonographically in order to identify the period of conversion
from palindromic rheumatism to the early-stage of rheumatoid arthritis.
Two patients, a 35-year-old man and a 44-year-old man, had been suffering
from episodic attacks and remission of oligoarthralgia for 15 years
and 6 years, respectively. Both patients were negative for rheumatoid
factors, and exhibited slightly elevated levels of C-reactive protein
and erythrocyte sedimentation rate at the times of the attacks. Radiograms
of the affected joints showed no erosion of the bones in either patient.
Ultrasonographic examination revealed both synovial effusion and
synovial proliferation in the 35-year-old patient, suggesting conversion
from palindromic rheumatism to rheumatoid arthritis, whereas only
synovial effusion was found in the 44-year-old patient, suggesting
the persistence of palindromic rheumatism. Ultrasonographic evaluations
of synovial proliferation in the knee joints provide data that can
be used to identify the period of conversion from palindromic rheumatism
to the early-stage of rheumatoid arthritis. |
