Imaging study of joint is important to differentiate various kinds of arthritis, and to evaluate the treatment response of the arthritis. Radiograph is the basic and first line imaging study of the joint, but there are overlapped imaging findings between arthritis. The objective of this review is to present a simplified approach to radiographic evaluation of arthritis and to help in making adequate decision to choose a further imaging study among ultrasonography, CT and MRI.

PURPOSE: To compare the MR imaging findings of experimentally induced pyogenic arthritis of rabbit knees with the corresponding histopathologic findings. MATERIALS AND METHODS: Infection was induced in 20 rabbit knees by direct intra-articular injection of Staphylococcus aureus. The animals were divided into four groups of five rabbits each, and spin-echo sagittal T1-and T2-weighted images were obtained 3 days, 1 week, 2 weeks, and 4 weeks, respectively, after staphylococcal inoculation. MR-pathologic correlation was performed, with emphasis on intra-and extra-articular soft tissue lesion characteristics. Soft tissue lesion signal intensity (SI) was classified as low, iso, or high on the basis of that of muscle, and high SI was further subdivided into three categories. RESULTS: At T2-weighted imaging, all soft tissue lesions showed high SI. Pathologic examination revealed the presence of inflammatory cell infiltration (n=2), abscess (n=1), granulation tissue (n=3), fibrosis (n=11), edema (n=4), congestion (n=9), and joint fluid (n=11). Except for the abscess, these lesions were irregular in shape and had variable SI (grade 1-3) and at T2WI could not, therefore, be differentiated. In nine kness, extraarticular soft-tissue lesions were demonstrated at T2WI and correlated with infectious soft tissue lesions such as inflammatory cell infiltration, abscess, granulation tissues and fibrosis; and non-infectious reactive soft tissue changes such as edema and congestion. CONCLUSION: In pyogenic arthritis, the MR imaging features of soft tissue lesions varied and were nonspecific, depending on the histopathologic abnormalities observed. Our results indicate that in assessing the extent of pyogenic arthritis with MR imaging, caution is required.

Epidermolysis bullosa (EB) is a rare inherited disease characterized by vesiculobullous lesion that arise in response to minimal trauma or shearing force to the skin. Epiderrnolysis bullosa herpetiformis-Dowling Meara, a variant of EB, has its onset at birth and can be a life threatening disease as it was in this case. We report a case of epidermolysis bullosa herpetiformis in a newborn with a generalized intraepidermal blisters noted at birth whose diagnosis was confirmed by electron microscope. A brief review of the literature is included.

The various pathologic conditions detected at CT and MRI and subsumed by the term "sacral tumor" include primary bone tumors, sacral canal tumors and metastases. Among these, metastases are much more common than primary bone tumors, of which chordoma is the most common. Although the imaging findings of sacral tumors are nonspecific, a patient's age and sex, and specific findings such as calcification or fluid-fluid levels, can help radiologists in their differential diagnosis. We describe the imaging findings of primary sacral tumors, emphasizing the MRI findings.

Immunoglobulin G4-related disease (IgG4-RD) can involve any organ. The majority of reported cases involve IgG4-RD of the biliary tract or pancreas, while only two cases of pericarditis have been reported. A 58-year-old man visited the outpatient clinic of our institution with a seven-day history of progressive dyspnea. Based on his transthoracic echocardiogram and transesophageal echocardiogram, he was diagnosed with constrictive pericarditis. The histopathology of his pericardiectomy revealed the cause of constrictive pericarditis to be IgG4-RD. Prednisolone (40 mg) was initiated after the pericardiectomy. As the patient's symptoms resolved, he was discharged and followed-up on an outpatient basis. This is the first case report of constrictive pericarditis caused by IgG4-RD in Korea.

Much attention has been paid to the insertion of central venous catheter(CVC) but their removal is a subject discussed rarely. After removal of a central venous catheter, rare but potentially life-threatening, transient cardiopulmonary collapse or neurological dysfunction had developed. The failure to appreciate these complications may be a significant factor in their high mortality. Early recognition and treatment may be made possible by a high index of suspicion. In this report, the clinical courses of two patients with central venous catheter removal distress syndrome are reviewed. Also guidelines for safe removal of CVC are formulated. An awareness of potential CVC removal complications is most important for their prevention and timely treatment. CVCs should be removed with the same degree of meticulous attention to detail that accompanies their insertion. Medical personnel should be reminded that removal of the catheter is an integral component of CVC management.
