We report a case of primary osteosarcoma of the breast which is rare and exhibits poor prognosis. A 52 years-old-woman was admitted with rapidly growing right mammary mass. A huge lobulated dense mass with speckled calcifications, suggesting malignancy, was observed on mammography. She underwent a radical mastectomy. Grossly, the mass measured 16 14 6 cm and showed grayish white hard lobulated tissue with focal hemorrhage and necrosis. Light microscopically, the tumor was confirmed as an osteosarcoma devoid of any epithelial components. In postoperative whole body bone scan, there was no evidence of the other malignancy. To the best of our knowledge, the present case is the first report of primary osteosarcoma of the breast in Korea.

The pancreatic pseudocyst as a sequela of pancreatitis or pancreatic trauma can occur at any site in the abdomen. Its detection seems to be increasing with modern imaging tools such as abdominal ultrasound or abdominal CT scanning. But recently, we experienced a case of a pseudocyst due to a ruptured pancreatic pseudocyst which was misdiagnosed as a simple hepatic cyst by abdominal ultrasonography or abdominal CT scan. A 12-year-old male presented with recurrent epigastric pain during the past 4 years. On the abdominal ultrasound and abdominal CT scan, there was an 8x7.5 cm sized sharply defined thin-walled cyst in the left lobe of the liver. First, percutaneous (cather) drainage guided by ultrasonography was done. An exploratory laparotomy was performed because of signs of hemoperitoneum. A 8x7.5 cm sized cyst was found at the left subhepatic space, which communicated with another smaller cystic lesion in the pancreatic head. Microscopic finding of the cyst showed infiltration of inflammatory cells and granulation tissue without ephithelial lined cells which is compatible to a pseudocyst. So we report this case with a review of literatures.

Recently MRI has been shown to be a sensitive and specific study for the noninvasive detection of meniscal tears and several MRI findings of bucket-handle meniscal tears have been reported. Therefore, the MRI findings of the menisci proven to be the bucket-handle tear with arthroscopy were evaluated and the typical MRI findings seen to be the bucket-handle meniscal tear of the knee were analysed. 76 patients with proven bucket-handle meniscal tears arthroscopically were reviewed retrospectively, in which MRI was performed in 24 patients. The 3 typical findings of bucket-handle meniscal tears were assessed: double PCL (posterior cruciate ligament) sign, flipped meniscus sign, and fragment in the intercondylar notch. In 245 cases of meniscus tears, bucket-handle meniscal tears were 76 cases (31.0%) with 52 cases at medial meniscus and 24 cases at lateral meniscus. As to clinical and physical findings of the bucket-handle meniscal tears, McMurray test, locking, joint line tenderness and giving way sense were presented in orders. The sites of bucket-handle meniscal tear were medial meniscus in 17 cases and lateral in 7 cases. The double PCL sign was seen in 10 cases (58.8%) of in medial bucket-handle meniscal tears and in 3 cases (42.9%) of 7 lateral bucket-handle meniscal tears. The flipped meniscus sign were seen in 3 cases (17.6%) of medial bucket-handle meniscal tears and in 3 cases (42.9 %) of lateral bucket-handle meniscal tears. Fragments were identified in the intercondylar notch in 8 cases (47.1%) of medial bucket-handle meniscal tears and in 3 cases (42.9%) of lateral bucket-handle meniscal tears. There were 19 cases (79.2%) in which at least one or more typical findings were presented on MR images. The MRI is a sensitive study for detection of bucket-handle meniscal tears but precise interpretation of MRI is needed for diagnosis of bucket-handle tears. In this respect, the above three typical findings are helpful and reproducible for diagnosis of bucket-handle meniscal tears with MR images; double PCL sign, fragment in the intercondylar notch and flipped meniscus sign.

Endovascular aortic repair is a new alternative to conventional surgical repair of aortic pathology. It is a less invasive technique and gives less hemodynamic stress to the patients who may have concomitant systemic diseases, compared with open aortic reconstruction. We report 2 cases of patients with thoracic aortic diseases, who underwent endovascular stent graft placement under general anesthesia. We also include a review of the literature about anesthetic management of endovascular aortic repair and present our opinions about the need to choose a suitable anesthetic technique for each patient, the method to recognize and handle the possible complications and hemodynamic changes to which we have to pay attention during procedures.

The purpose of this study is to analyze the effects of IFN-r(interferon-r) on HLA-DR and ICAM-l(intercellular adhesion molecule 1) expression, a measure of cancer progression. We uses human bladder tumor cell lines of RT4(GI) and T24(GIII), a part of each type of cultured cells were treated by 200U/m IFN-r and divided into 3 groups( 24-hour, 48-hour, 72-hour) according to the time after the IFN-r treatment. Each cell was then indirectly immunofluorescence stained and analyzed using the Fluorescence Activated Cell Sorter(FACS). We founded that bladder cancer cells, when they are not treated by IFN-r, do not seem to show much HLA-DR constitutive expression. When bladder cancer cells are treated by IFN-r, the effects of IFN-r on HLA-DR expression rate seem to depend on the degree of differentiation of bladder cancer cells : well-differentiated bladder cancer cell shows higher HLA-DR expression rate when it is treated by IFN-r, while poorly-differentiated bladder cancer cell does not show much changes in HLA-DR expression rate even after it is treated by IFN-r. Bladder cancer cells of higher degree of malignancy show higher ICAM-1 constitutive expression rate and enhanced expression by IFN-r.

PURPOSE: To evaluate the plain radiographic and CT findings of the necrotizing fasciitis. MATERIALS AND METHODS: We retrospectively reviewed the radiologic findings of 4 cases with necrotizing fasciitis. Three cases were proven pathologically. We evaluated pattern and extent of the gas shadows in plain films. CT findings were analysed, with emphasis on : (a) gas pattern, (b) extent, (c) location and involved site, (d) associated focal abscess, and (e) swelling of the adjacent muscles. RESULTS: On plain radiographs, four cases showed streaky or mottled gas densities in the pelvis, three cases in the perineum, one case in the abdomen, and two cases in the thigh. On CT images, gas pattern was mottled and streaky appearance with swelling of the adjacent muscles. Gasshadows located in the extraperitoneal space in four cases, fascial layer in four cases, and subcutaneous layer infour cases. There were gas shadows in pelvic wall, perineum, abdominal wall, buttock, thigh, and scrotum. Focallow density lesion suggestive of focal abscess was not visualized. CONCLUSION: Plain radiography is useful forearly diagnosis of the necrotizing fasciitis and CT is very useful for detection of precise location and extent of the disease. CT is also useful for differentiation of necrotizing fasciitis from focal abscess and cellulitis.
