Primary biliary cirrhosis, a chronic, progressive, and often fatal cholestatic liver disease, is characterized by destruction of intrahepatic bile ducts, portal inflammation and scarring, and the eventual development of cirrhosis and liver failure. We reviewed four cases of primary biliary cirrhosis primarily suspected with peritoneoscopic liver biopsy specimens. All patients were female and their age ranged from 29 to 50 years(median age: 43.8 years). Presenting symptoms were typically pruritus and/or upper abdominal discomfort. On physical examination, interus was presented in 3; hepatomegaly in 3; chronic liver disease stigmata in one. Co-existing autoimmune diseases such as Hashimoto' thyroiditis and Sjoegren' syndrome were found in 2 cases. Biochemical tests of liver function revealed a cholestatic pattern. An antimitochondrial-antibody test was positive in 2 out of 3 patients(75%). Increase levels of serum immunoglobulins, especially of IgM, were evident in 3 cases. Histologic staging(Ludwig et al.) disclosed stage I lesion in one, stage III in two, and stage IV in the remaining one.

PURPOSE: The purpose of this study is to evaluate the usefulness of fat suppression technique for MR imaging of the knee. MATERIALS AND METHODS: Twenty-eight knees of 26 patients were imaged at a 1. 5 T MR system. Sagittal and coronal T2-Weighted spin echo images (SET2) and sagittal fat suppression SET2(FSSE) were obtained in all cases. We used a chemical shift imaging method for fat suppression. We compared FSSE with SET2 in terms of the conspicuity of lesions of menisci, cruciate ligaments, cartilage, bone and soft tissue of the knee. RESULTS: Meniscal lesions were detected on FSSE and SET2 as well. FSSE depicted the lesion more conspicuously in 6 cases. For the depiction of ACL tear, SET2 was superior to FSSE in 5 cases. FSSE was better for the visualization of the normal structure of cartilage and it also depicted the cartilaginous lesions more conspicuously in 3 cases. Though bone bruise could be detected on both techniques, FSSE was better. CONCLUSION: FSSE could provide the improved delineation of menisci, cartilage, bone bruise and other soft tissues except the injuries of anterior cruciate ligament. Although FSSE is a reliable method, it can not replace SET2. It may be used as a complemental method in the imaging of the knee.

Mucoepidermoid carcinoma was initially recognized as occurring only in the salivary gland and only later was it appreciated that it occurred in the bronchus and trachea as well. Mucoepidermoid carcinoma of bronchial gland origin is extremely rare, and little is known about their natural history. This carcinoma is derived from the minor salivary gland of the proximal tracheobronchial tree and it is divided into low-grade and high-grade by gross, histologic, and ultrastructural criteria. Also Its clinical and biologic behaviors are closely related with histologic grade of carcinoma. We have experienced a rare case of bronchial mucoepidermoid carcinoma associated with adenocarinoma which obstructed the left main bronchus and was successfully removed by the pneumonectomy.

PURPOSE: It is difficult to determine objectively therapeutic response in rheumatoid arthritis. This study was carried out in order to assess the feasibility of MR imaging to determine disease status following antirheu-matoid medication. MATERIALS AND METHODS: Eight patients with rheumatoid arthritis underwent MR studies before treatment and approximately one year after the beginning of antirheumatoid medication. Coronal images were obtained, using a T1- and T2-weighted spin echo(n=8), contrast-enhanced T1-weighted images(n=8) and dynamic contrast-enhanced images(n=4). Bone erosions, synovial hypertrophy and bone marrow enhancement in pre- and post-medication studies were compared. On dynamic study, enhancement ratio(E) of pannus was measured(E=SNR at 30sec/SNR at precontrast). Changes of MRI findings and enhancement ratio between pre- and post-medication were compared with disease status as assessed by clinical index. RESULTS: In three patients, improvement of bone marrow edema and synovial hypertrophy was noted, and in addition, there was no evidence of newly developed boneerosion. In two of these patients, complete remission was noted on the basis of the ARA criteria. In another three patients, despite improvement of bone marrow edema and synovial hypertrophy and improved clinical parameters including morning stiffness and ESR, discrete and newly developed bone erosions were noted. In one patient with apoor response to antirheumatoid medication, aggravation of bone marrow edema and synovial hypertrophy was seen, but no definite change in bone erosions was noted. In the remaining one patient, no remarkable changes were seenin bone marrow edema, synovial hypertrophy or bone erosion. Clinically this patient showed no morning stiffness or elevated ESR. The enhancement ratio of pannus decreased in all 4 cases, especially where there were complete remission. CONCLUSION: Synovial extent, bone marrow enhancement, bone erosions and enhancement ratio of pannusmay be good parameters for monitoring disease activity in the follow-up of the patients with rheumatoid arthritis.
