Diagnosis and treatment of a patient with a congenital anomaly of the midgut with persistent symptom in adult can be difficult because it is particularly in adults. Reversed rotation of the midgut is the rarest of all malrotation anomalies. We report a case of reversed intestinal rotation and review the embryology, clinical presentation, and radiographic findings of this disorder. Although this anomaly is rare, it may be diagnosed by the knowledge of embryology and anatomy.

Purpose:This study was done to arrange the cases showing temporally hyperperfusion in the periphery of the liver, to check the etiology and mechanism, and to find out the new radiologic role on diffuse liver disease. Materials and Methods:We reviewed 12 cases of showing transient arterial hyperperfusion in the just peripheral portion of the liver on the arterial dominant phase on dynamic CT and the absence of abnormal perfusion between central and peripheral portion on tissue equilibrium phase. We retrospectively analyzed final diagnosis and the presence of main portal vein thrombi, and cavernous transformation. 1) Results:Final diagnosis in 12 cases was as follows: diffuse liver disease was in seven cases, pancreatitis in three and pyogenic portal thrombosis in two. Main portal vein thrombosis were detected all cases of pancreatitis and pyogenic portal thrombosis. In seven diffuse liver disease, two cases shown thrombosed, two cases shown normal and the other cases are collapsed. Cavernous transformation was in three cases of pancreatitis and two of diffuse liver disease. Conclusion:We think that the causes of this phenomenon maybe as follows: the difference of the hemodynamic compensation mechanism between central and peripheral zone of the liver, presence of microscopic thrombi in peripheral portal branch which cannot be detected by imaging technique, hypercoagulability in portal area, the systematic destruction of terminal portal branch and the development of ectopic portal pathway.

Plasmacytoma is a neoplastic proliferation of plasma cells and commonly occurs in the bone marrow. However, it may develop in any tissue throughout the body. Extramedullary plasmacytomas constitute 3-5% of all plasma cell neoplasms, and the most common site of these tumors is the upper respiratory tract. Extramedullary plasmacytoma of the omentum is extremely rare. We report a case of extramedullary plasmacytoma of the omentum presented as a huge omental cystic mass on ultrasonogram and CT scans. It was confirmed by immunohistochemical study of the resected specimen. (Korean J Gastroenterol 2002;39:142-145)

Undifferentiated carcinoma with osteoclast-like giant cells is a rare neoplasm of exocrine pancreas. Till recently, some cases have been reported, however histogenesis of the tumors are controversial and their characteristic findings have not been described yet. Thirty five-year-old men and 75-year-old men were presented with upper abdominal pain and a palpable mass. On computed tomography, one case showed a well enhancing solid tumor with low density and the other was showed a mainly cystic tumor with peripheral enhancement in the body and tail of the pancreas. One case accompanied multiple metastatic liver masses with subhepatic lymph node enlargement. Tumor staining was seen on angiography. Biopsy and pancreatectomy were performed. Pathological findings revealed tumors composed of neoplastic spindle shaped or pleomorphic large cells with scattered non-neoplastic osteoclast-like giant cells. In one case, there were small foci of adenocarcinoma components in the periphery of the tumor. On immunohistochemical stain, neoplastic cells showed focal positivity for epithelial membrane antigen and vimentin. Tumors were diagnosed as undifferented carcinoma with osteoclast-like giant cells. We report these rare cases with a review of literature. (Korean J Gastroenterol 2006;48:355-359)

Cure by single modality for advanced hepatocellular carcinoma (HCC) is difficult. Therefore, multidisciplinary approaches are needed to get a better outcome for advanced HCC. In this paper, we report a case of advanced HCC treated with curative surgical resection after downstaging by hepatic arterial infusion chemotherapy (HAIC). A 50-year-old male patient had a maximum 16.0 cm sized HCC in the right lobe. He achieved a partial response after 2 cycles of HAIC with 5-FU (750 mg/m2) and cisplatin (25 mg/m2). After completion of 6 cycles, he received a curative right hepatectomy and the histopathology revealed 95% of tumor necrosis. He is under follow-up without recurrence at 14 months of surgery. This case suggests that surgery after downstaging by HAIC may provide good clinical outcome in advanced HCC.
