Anticoagulant peptides obtained from human fibrinogen degradation products by plasmin have been studied. These peptides caused a siginificant prolongation of the plasma prothrombin time and partial thromboplastin time of normal plasma. Moreover, they showed an inhibitory effect on factors VIII, IX, XI, and XII in the intrinsic blood coagulation system. It is suggested that they might have feed-back inhibition against these factors and control thromboplastogenesis in blood coagulation, especially in the intrinsic clotting mechanism. 相似文献

Myxofibrosarcoma (MFS) has a spectrum of malignant fibroblastic lesions with variably myxoid stroma and pleomorphism. A 67-year-old man with a bulky mass on his chest wall was diagnosed with MFS. He underwent F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography for detection of metastasis. FDG positron emission tomography /computed tomography showed inhomogeneous high FDG uptake (max standardized uptake value, 10.1) in the bulky tumor with no evidence of metastasis, and the tumor was successfully resected. FDG uptake seemed to be reflected by the broad spectrum of pathologic heterogeneity. And MFS should be considered when making a diagnosis of inhomogeneous FDG-avid lesions in the bulky masses of soft tissue. 相似文献

We present two cases of tuberculous pericarditis that were diagnosed using 18F-fluorodeoxyglycose (18F-FDG) positron emission tomography (PET). Here, we highlight the value of 18F-FDG-PET for demonstrating tuberculous pericardial involvement as well as disease dissemination and activity. The patients
received antitubercular treatment, and their symptoms and findings resolved accordingly. 相似文献

Kaposi sarcoma is an acquired immunodeficiency syndrome-related disease that mainly involves the skin, gastrointestinal gut, and lungs. Whole-body 18F-fluorodeoxyglucose-positron emission tomography and computed tomography (FDG-PET/CT) scanning is useful for simultaneous detection of multiple lesions of Kaposi sarcoma. We present a 67-year-old man with a history of infection with human immunodeficiency virus who presented with numerous cutaneous lesions. FDG-PET/CT images showed lesions in the skin, lung, and lymph nodes. The gastrointestinal lesions were detected using gastric fiberscopy (GF) and colon fiberscopy (CF). After Kaposi sarcoma therapy, the uptake in the lesions of the skin, lung, and lymph nodes decreased, but new lesions were detected in the pancreas and lumbar spine. He had pancreatitis and Candida spondilitis. Whole-body FDG-PET/CT is useful for detecting lesions and determining the extension to which the disease has spread, adding the gastrointestinal lesions by GF and CF. After therapy, FDG-PET/CT can be used to demonstrate which lesions remain active and to determine the overall response to treatment. In this case, we show how useful FDG-PET/CT is and how difficult it is to treat Kaposi sarcoma. 相似文献

Mycobacterium tuberculosis (TB) is one of the most prominant diseases frequently causing false positive lesions in oncologic surveys using 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT), since TB granulomas are composed of activated macrophages and lymphocytes with high affinity for glucose. These pitfalls of 18F-FDG PET/CT are important for radiologists. Being familiar with 18F-FDG images of TB could assist in preventing unfavorable clinical results based on misdiagnoses. In addition, 18F-FDG PET/CT has the advantage of being able to screen the whole body, and can clearly detect harboring TB lesions as high uptake foci. This article details the spectrum and pitfalls of 18F-FDG PET/CT imaging in TB. 相似文献
