目的提高对原发性肺动脉肉瘤(PAS)的认识和早期诊治率。方法结合3例肺动脉肉瘤患者的的临床资料和国外有关文献,对肺动脉肉瘤及肺血栓栓塞症(PTE)的临床特点进行分析。结果肺动脉肉瘤的临床表现和肺血栓栓塞症相似,但前者多有发热、体重下降,无下肢深静脉血栓形成,胸部增强CT显示肺动脉扩张,主肺动脉及左、右肺动脉内大量肿块阴影,管腔外肿块阴影,溶栓抗凝治疗无效等,确诊需手术。结论肺动脉肉瘤易误诊为肺血栓栓塞症,临床医师应提高认识。 相似文献

原发性肺动脉肉瘤的诊治进展 总被引:1,自引:1,他引:0
原发性肺动脉肉瘤是一种起源于肺动脉并主要累及肺循环的罕见肿瘤,其临床表现多样且无特异性,易复发和转移.本病与慢性肺血栓栓塞疾病在临床和影像学表现方面存在相似性而容易混淆,不同影像学诊断方法联合有助于提高术前诊断率.治疗以手术为主,联合化疗和放疗可延长生存期.本病总体预后差,与肿瘤切除程度、病理类型等相关. 相似文献

慢性血栓栓塞性肺动脉高压是一种较为常见的疾病,虽然目前认为慢性血栓栓塞性肺动脉高压是急性肺栓塞的一种临床结局,但部分慢性血栓栓塞性肺动脉高压患者并无明确肺栓塞病史.由于临床医师对此疾病的认识尚不够深入,故往往是在对呼吸困难患者进行超声心动图检查时才怀疑此疾病.慢性血栓栓塞性肺动脉高压的确诊依赖于通气/灌注肺扫描和肺动脉造影.本文对慢性血栓栓塞性肺动脉高压的发病机制、危险因素和临床表现以及诊断研究进展进行综述. 相似文献

A 69-year-old woman presented with a 4-month history of dyspnoea and radiating upper-right quadrant pain and oedema in her lower extremities for more than 20 days. The ultrasonographic study of the heart revealed the adherence of a substantive hypoechoic mass (73 x 34 mm) to the antelateral wall of the pulmonary artery and resultant pulmonary stenosis. Computed tomographic imaging of the pulmonary artery revealed an irregularly shaped filling defect (approximately 41 x 39 x 59 mm) in the main pulmonary artery. The boundary of the defect was irregular, but demarcation with healthy tissue was clear. After surgical treatment, the histologic and immunohistochemical assays revealed a primary pulmonary artery rhabdomyosarcoma. Pulmonary artery rhabdomyosarcomas are usually misdiagnosed as other pulmonary artery obstructive diseases. There should be a greater focus of clinical attention and resection is the appropriate surgical treatment for such malignant tumours. 相似文献

Pulmonary artery sarcoma is a highly malignant tumour. Therefore, making the diagnosis is very important. We describe a case which presented with dyspnea on exertion and was initially diagnosed as saddle pulmonary embolism per CT thorax with contrast. Despite adequate anticoagulation, symptoms still progressed. Follow-up CT thorax showed an extension of the presumed filling defect or clots into the left main pulmonary artery with new lung nodules. This prompted suspicion that this may not be a pulmonary embolism. Biopsy of the lung nodule revealed high grade soft tissue sarcoma with primary source from the pulmonary artery. Our case highlights that pulmonary artery sarcoma should always be included in the differential diagnosis of pulmonary embolism especially, if symptoms still progress while on adequate anticoagulation, or any pulmonary nodules develop on follow-up exam. 相似文献

Pulmonary artery sarcoma is a rare tumor that is frequently misdiagnosed as chronic pulmonary embolism. With heightened clinical awareness and advancement in technology, the diagnosis is now increasingly being made preoperatively. Previous literature has described the disease to be uniformly fatal, with surgical resection as the single most effective modality for short-term palliation. We present the case of a patient in whom pulmonary artery sarcoma was diagnosed preoperatively and who underwent surgical resection with no evidence of recurrence during long-term follow-up, suggesting that early identification and aggressive surgical intervention has the potential to be curative. 相似文献

Manifestations of pulmonary vasculitis syndromes and collagen vascular diseases are extremely variable and diagnostically challenging. Pulmonary involvement is frequent in the primary systemic vasculitis (PSV) syndromes Wegener??s granulomatosis, Churg-Strauss syndrome and microscopic polyangiitis. PSV have to be discriminated from pulmonary involvement in other rheumatic diseases, secondary vasculitis due to infections and vascular affections secondary to lymphoproliferative diseases. Pulmonary involvement occurs in all types of collagen vascular diseases, and morphology may be identical in different types of rheumatic diseases as well as idiopathic interstitial lung disease. The diagnostic challenge here is to discriminate collagen vascular disease from idiopathic lung disease, from adverse drug effects and infections. In many cases, not all diagnostic criteria can be found in a single biopsy; therefore, the selection of appropriate biopsy material as well as a correlation with clinical, serological and radiological parameters is essential. 相似文献

Pulmonary artery sarcomas are rare, difficult-to-diagnose tumors that frequently mimic chronic pulmonary thromboembolism. We report the cases of two female patients with clinical signs of dyspnea and lung masses associated with pulmonary artery filling defects on chest CT angiography. We performed 18F-fluorodeoxyglucose positron emission tomography, which revealed increased radiotracer uptake in those lesions. Pulmonary artery sarcoma was subsequently confirmed by anatomopathological examination. We emphasize the importance of this type of tomography as a noninvasive method for the diagnosis of these tumors. 相似文献

??Abstract??Pulmonary Infiltrates with eosinophilia??clinically referred to as eosinophilic lung diseases (ELD)??are a heterogeneous group of disorders characterized by pulmonary infiltration associated with alveolar eosinophilia with or without peripheral eosinophilia.They are classified generally as primary ELD??secondary ELD??and other diseases occasionally associated with eosinophils.Clinical manifestation of these disorders can be varied??and their presentation can be mild or fatal.Accurate diagnosis is based on a full history and examination??along with clinical manifestations??radiological imaging and laboratory findings.Corticosteroids are the mainstay of treatment for ELD and most patients will require prolonged courses of daily steroids.The dose and use duration of corticosteroids should be individualized. 相似文献

Pulmonary actinomycosis. 总被引:14,自引:0,他引:14
Pulmonary actinomycosis is a rare but important and challenging diagnosis to make. Even when the clinical suspicion is high, the disease is commonly confused with other chronic suppurative lung diseases and with malignancy. An early, accurate diagnosis will prevent the considerable psychological and physical morbidity, including unwarranted surgery, associated with delayed diagnosis. The clinical, radiological and therapeutic characteristics of the infection are reviewed here. Respiratory physicians should be aware of this important differential when investigating patients for persistent pulmonary shadowing. This will expedite the diagnosis of an otherwise highly treatable condition with an excellent prognosis if picked up early. 相似文献
