To evaluate the correlation between plain radiography and bone scintigraphy in the diagnosis of sacroiliitis, we analyzed 50 sacroiliac joints of 25 patients diagnosed as ankylosing spondylitis, The sacroiliac-sacral(SIS) ration significantly increases in patients with sacroiliitis of Grade l, ll, lll and was normal in completely ankylosed sacroiliac joints(Grade IV). However, there was no correlation between the degree of increase of SIS ratio and that of the radiographic changes in Grade l. ll. lll groups. Bone scintigraphy might be useful in the early detection of sacroiliitis. but plain radiography is more valuable in evaluating progression.

In the diagnosis of the meniscal tear of the knee, the high accuracy of the MRI diagnosis is well-known, but the accuracy of the MRI in the diagnosis of the very pattern of the tear of menisci is not well-established. The purpose of this study is to give some informations to consider in the diagnosis and therapeutic planning of torn menisci. The authors performed a retrospective study comparing the MRI and arthroscopic findings of 141 knees which had undergone arthroscopic surgery from Mar. 1997 to Mar. 1998. The results are as follows. In the diagnosis of tear of the menisci, MRI had sensitivity of 91%, specificity of 96%, accuracy of 95%. The mismatch of the tear patterns of the menisci between MRI and arthroscopic findings was identified in 59%, especially high in flap tear(100%), complex tear(84%), peripheral tear(55%). In conclusion, MRI is very accurate in the diagnosis of the tear of menisci, but the tear patterns of the menisci cannot be accurately determined by MRI. In the cases of flap tears, complex tears and peripheral tears, it is more difficult to determine the tear patterns of the menisci by MRI. False-negative rate of MRI was especially high(44%) in the peripheral tear type. So, other clinical correlations should be made in determination of the presence of the tear in the diagnosis of peripheral tear of the menisci.

Calcium pyrophosphate dihydrate (CPPD) crystal deposition disease is one of the most common causes of arthralgia in elderly. The acute form (pseudogout) may present as acute monoarticular or polyarticular arthritis. It is often accompanied by high fever and sometimes simulates acute infectious condition. The knee is the joint most frequently affected by pseudogout but other sites such as wrist, shoulder, ankle, elbow and hands may be affected. A few cases involving cervical and lumbar spine mistaken for CNS infection have also been described in foreign countries. We report here a case of CPPD crystal deposition disease mimicking meningitis.

Objective: The purpose of the study is to describe the magnetic resonance imaging (MRI) findings and to investigate useful sequences of MRI in inflammatory myopathies. A third goal is to correlate MRI findings with the grade of histopathologic severity. Methods: Sixteen patients (13 women, 3 men), aged 21~74 years (median age of 49) with inflammatory myositis (examined with both MRI and muscle biopsy) were studied. Ten patients were diagnosed with polymyositis and 6 with dermatomyositis. Conventional T1-weighted (SE 366/12) and T2-weighted (SE 4766/90) fast spin-echo and fat-suppressed T1-weighted MR images with contrast enhancement (FSAT T1 CE) were obtained. Ratios between the signal intensities of a muscle and the signal intensities of subcutaneous fat in the same tomographic sections were calculated to objectively represent the degree of signal intensities. Semi-quantitative grading of severities in muscle biopsy specimen was examined based on invasion of inflammatory cells and necrosis, degeneration and regeneration of muscle fiber by a neuromuscular pathologist. Results: FSAT T1 CE could objectively describe the severity of involvement in inflammatory myopathies. The quadriceps muscle group, especially the vastus muscle tended to be most severely and frequently involved in inflammatory myositis with FSAT T1 CE (statistically insignificant). The vastus intermedius muscle was more severely involved in dermatomyositis than polymyositis. The signal intensity of abnormal muscle sampled by biopsy correlated positively with the grade of muscle biopsy. Conclusion: MRI shows promise in identifying pathologic muscle in patients suspected of having one of the inflammatory myopathies. The degree of signal intensity on MRI may reflect the severity of grade in muscle biopsy.

The characteristics of hip pain in avascular necrosis of the femoral head is difficult to assess objectively, and not well described according to each stages of disease. This study was undertaken to determine whether a correlation exists between specific pain characteristics and radiological findings including collapsed pattern, joint effusion, synovial hyperplasia etc. One hundred and nine hips in 77 patients were clinically classified according to the severity of pain that was based on the objective numeric scales(0 - 10), and the characteristics of pain were subdivided into location, nature, severity, joint motion, time, pattern, other aggravating factor and etc. The pain natures were compared with the findings on simple radiographs and MRIs. The amount of joint effusion and synovial thickening were measured on serial cut of MRIs(lesser trochanteric, center of femoral neck and greater trochanteric level) by our grading. The clinical studies have shown that the severity of pain in Ficat stage IIA(Ave. 6.0) was similar to that in stage IIB(Ave. 6.8), m(Ave. 6.4) anl IV(Ave. 6.9). Patients in Ficat stage IIA complained sharp, buttock pain associated with initial motion. Bone marrow edema was more observed in later stages on MRL Effusion and synovial thickening of the hip joint were rather significant in later stages without change of the severity of pain. In statistical analysis, there was a clear relationship between the size of lesions and both joint effusion and synovial thickening. The severity scores correlated significantly with joint effusion and synovial thickening. Hence we concluded that the patients pain characteristics could aid in the evaluation of the disease status.

Localized nodular myositis is an uncommon benign inflammatory myopathy of unkonwn cause affecting skeletal muscle and, presenting as a localized painful swelling within the soft tissue of an extremity. Histological examination reveals lymphocytic infiltration, scattered muscle fiber necrosis and regeneration, and interstitial fibrosis. MRI finding is an enhancement with increased signal intensity around the lesion. We report two cases of localized nodular myositis presenting as pseudothrobothrombophlebitis. We believe this is the first case report of localized nodular myositis in Korea.

Objective: To investigate the clinical usefulness of serial measurement of erythrocyte sediment rate(ESR) and C-reactive protein(CRP) for monitoring the radiological progression in early rheumatoid arthritis(RA). Methods: Thirty one patients with RA according to the 1987 ACR criteria, with joint symptoms for less than one year, and who had not previously received disease modifying antirheumatic drugs(DMARDs) were assessed from Oct. 1994 to Aug. 1998 in retrospective study. Area under curve(AUC) of ESR and CRP were calculated in these patients. Joint damage in the hands was assessed by modified Sharp`s method. Results: Male to female ratio was 1: 3.4. Median age of this group was 45.8±13.2 years. Patients who had positive rheumatoid factor were 82%. Mean duration until first visit was 271.9±145.8 days. At the first clinic visit, mean ESR and CRP were 50mm/hr and 2.0mg/dL. Mean erosions and joint space narrowing score by modified Sharp`s method were 55.2 and 12.4, respectively. Correlation analysis showed that ESR AUC and CRP AUC were significantly associated with radiologic progression. Conclusions: Elevated over-time ESR and CRP provide a convenient short term correlation with radiologic outcome(i. e. erosions). Elevated over-time ESR and CRP can be used as a guide for therapy.
