Mesenteric Fibromatosis Presenting as Fever of Unknown Origin

We report a case of fibromatosis, soft tissue tumors that are benign histologically, but exhibit behavior intermediate between benign and malignant diseases. Mesenteric fibromatosis grows vigorously without a general inflammatory reaction, and its symptoms are the result of obstruction and/or compression of the intestine. However, in our case, the general inflammatory reactions of fever and C-reactive protein (CRP) elevation was present at an early stage. Because this inflammatory reaction disappeared after surgical resection, it may have been induced by some inflammatory factors produced in the tumor, such as those produced in inflammatory fibrous histiocytoma. We found that computed tomography was useful in the detection of the cause of fever of unknown origin, and suggest that it should be recommended in cases of long-lasting unexplainable fever.     

Mesenteric panniculitis: an update

In 1924, mesenteric panniculitis was first described in the medical literature by Jura et al. as ‘retractile mesenteritis.’ It represents a spectrum of disease processes characterized by degeneration, inflammation and scarring of the adipose tissue of the mesentery. The clinical presentations vary according to the stage of the disease and they include abdominal pain, weight loss, nausea and vomiting. Computed tomography findings are usually diagnostic. The gross findings include thickening of the mesentery, mass lesions and adhesion to the surrounding organs. Histologically, there is a chronic inflammatory process involving the adipose tissue with fat necrosis, inflammation and fibrosis. Herein, the authors address the clinicopathological features, course, treatment and pathogenetic mechanisms of mesenteric panniculitis.     

An Abdominal Soft Tissue Mass Caused by Mesenteric Fibromatosis

Therein we describe a case of a reoccurring soft tissue mass that was well shown on plain abdominal radiographs as well as barium and angiographic studies. The rare condition of mesenteric fibromatosis was the pathological diagnosis. The case report and its interesting aspects are discussed.     

自发性高血压大鼠与WKY大鼠肠系膜动脉的左旋精氨酸舒张

应用微量生物测定法发现左旋精氨酸（L－arg）可使成年SHRsp与WKY肠系膜动脉的有无内皮肌条舒张，且SHRsp者均弱于WKY。在一定浓度下，L－arg可使SHRsp与WKY有内皮肌条的舒张显著强于去内皮者。但SHRsp有内皮肌条的L－arg舒张弱于WKY。SHRsp与WKY的去内皮肌条的L－arg舒张则无显著差异。主旋硝基精氨酸（L－NNA）使WKY的L－arg舒张显著减弱，对SHRsp则无显著影响，表明SHRsp与WKY肠系膜动脉的L－arg舒张具有内皮依赖的性质。SHRsp内皮细胞的L－arg－NO通路可能有功能变化，WKY的内皮则可能有较大的L－arg储备。同时SHRsp的肠系股动脉内皮及肌细胞受L－NNA抑制的影响不显著，提示其他机制的存在。

Multidetector Computed Tomographic Imaging of Erdheim-Chester Disease

Erdheim-Chester disease is a rarely reported disease that can affect nearly every organ and chiefly infiltrates the connective, perivascular, and adipose tissue. The disease is a form of non-Langerhans-cell histiocytosis characterized by the proliferation of foamy histiocytes; its cardiovascular complications carry a severe prognosis. We present the case of a 29-year-old woman who was admitted for analysis of her angina. Our evaluation with use of cardiac multidetector computed tomographic angiography revealed large mediastinal soft tissue that compressed the patient''s left anterior descending coronary artery. To our knowledge, this is the first report of the use of low-dose, dual-source, 256-slice multidetector computed tomography to characterize Erdheim-Chester disease that exclusively caused angina and stenosis of a coronary artery in a young adult.
