肺内血管肉瘤(epithelioid angiosarcoma)是一种罕见的肿瘤,因其导致出血而在肺内形成结节伴“晕征”的征象,随着出血的发生及吸收易形成“此起彼伏”的改变,影像表现特殊。同时伴有脑内转移的更为罕见,脑内的血管肉瘤同样易出血,核磁共振影像表现具有特异性。本文通过报道1例在肺部表现为多发结节伴晕征,随着多次随访出现“此起彼伏”改变,以及脑内多发转移的血管肉瘤,介绍该病的临床表现、影像学表现、鉴别诊断,分析并总结肺内出现结节伴晕征的疾病的鉴别诊断思路,为临床医生早期诊断该病提供参考。  相似文献

We report a case of angiosarcoma complicated by bilateral massive bloody pleurisy (hematocrit of 7.2%) in an 83-year-old woman. An autopsy revealed hemorrhagic tumors infiltrating both the diaphragm and serosal surface of the peritoneum. Histological examination confirmed an anastomosing vascular channel pattern of the tumor cells with characteristic immunohistochemical findings for angiosarcoma, such as positive staining for vimentin, CD31, CD34, D2-40, and factor VIII-related antigen. The tumor was thought to have originated from a small vessel on the serosal surface of the duodenum. We also reviewed cases of hemothorax associated with angiosarcoma, which suggested that primary or metastatic pleural angiosarcoma should be considered a cause of spontaneous hemothorax, especially in patients with bilateral and/or intractable hemothorax.  相似文献

ABSTRACT: Epithelioid angiosarcoma of the bone represents a challenging diagnosis by bone marrow biopsy. We present a case of a multicentric high grade angiosarcoma of the bone with epithelioid features. On the basis of the clinical presentation, the radiological findings, and the appearance of loosely clustered tumor cells detected in the initial bone marrow biopsy, the main differential diagnoses considered were a poorly differentiated non-secretory multiple myeloma and metastatic carcinoma. Subsequent morphologic, immunohistochemical and electron microscopic examination of tissue samples clarified the nature of the tumor as epithelioid angiosarcoma. We discuss potential pitfalls in clinical and morphological diagnosis. The strong reactivity of the tumor cells with the nonspecific but ubiquitous mesenchymal marker vimentin in similar cases should direct early attention to the rare malignant bone tumor, epithelioid angiosarcoma, with subsequent confirmation of this diagnosis with specific immunohistochemical endothelial cell markers and/or electron microscopy.  相似文献

Pulmonary angiosarcoma is an unusual cause of diffuse pulmonary hemorrhage. Angiosarcomas are rare malignant vascular tumors accounting for 1% to 2% of all sarcomas. Angiosarcomas have been detected in nearly all organs, but lung involvement is unusual, accounting for less than 7%. The literature describes approximately 10 isolated cases of primary pulmonary angiosarcoma as opposed to the more common metastatic type. Given that primary and metastatic types are clinicopathologically similar, the presence of a distant primary sarcoma must be ruled out before a diagnosis of primary pulmonary angiosarcoma can be made. A pathological diagnosis requires a finding of polygonal or oval cells with atypical irregular nuclei and vascular spaces lined with such cells surrounded by hemorrhagic phenomena. Immunohistochemical analysis is positive for specific endothelial cell markers such as CD31 and factor VIII, and coexpression of keratin is a frequent finding.  相似文献

目的研究CT血管征对肺微小结节良恶性判定的临床意义。方法分析我院95例肺微小结节患者CT影象学资料,依据病理诊断将其分为研究组与对照组,研究组恶性病变,对照组良性病变。对比两组CT血管征诊断的敏感性差异、病变类型与CT血管征分型间的关系、不同时点动态增强CT值、PH、SPH/PPH间差异。结果研究组血管征阳性者CT平扫、动态增强30s、90s、180s、300s、480s CT值与对照组CT平扫、各时点动态增强CT值相较,均呈明显差异(P0.05)。研究组血管征阳性者动态增强CT特征性参数中,PH、SPH/PPH与对照组相较,均呈明显差异(P0.05)。结论肺微小结节CT血管征有辅助诊断意义,可以指导临床判定肺微小结节的良恶性病变。动态增强扫描可以提高CT血管征对肺微小结节良恶性的确诊率。  相似文献

Pulmonary angiosarcoma is an uncommon vascular and usually secondary tumor. Only a few primary cases of pulmonary angiosarcoma have been described. We report a case of primary pulmonary angiosarcoma in an adult man who presented with hemoptysis. Chest x-ray film and chest CT showed a right para-cardiac opacity associated with diffuse alveolar consolidation of the right basal lobe. Right inferior lobectomy has been performed. Pulmonary angiosarcoma was diagnosed on histological and immuno-histochemical studies of the operative specimen. The primitive character was retained after ruling out all other tumor localizations. The clinical outcome was rapidly fatal. This observation is added to the other rare cases published of primitive pulmonary angiosarcoma. It confirms the poor prognosis and the extremely hemorrhagic nature of this tumor. Isolated necrotic parenchymatous mass was an original radiological pattern observed in this patient.  相似文献

Four cases of hepatic angiosarcoma are reported with a review of 99 other cases in the English literature. Angiosarcoma of the liver is associated with chronic exposure to thorotrast, vinyl chloride, arsenicals, radium and possibly copper and with chronic idiopathic hemochromatosis. Although 40% of patients have hepatic fibrosis or cirrhosis at autopsy, the nature of the association between chronic liver disease and hepatic angiosarcoma is unknown. The clinical presentation of hepatic angiosarcoma is nonspecific with abdominal pain, weakness and weight loss common complaints and with hepatomegaly, ascites and jaundice common findings. Liver function tests are usually abnormal but there is no one liver function test or set of tests specific for the tumor. The occurrence of thrombocytopenia and disseminated intravascular coagulation is characteristic of hepatic angiosarcoma and may be related to local consumption of clotting factors and formed blood elements in the tumor. Catastrophic intraabdominal bleeding is also characteristic and occurs in one-fourth of all cases. This complication is likely related to the high incidence of clotting abnormalities and the vascular nature of the neoplasm. Selective hepatic arteriogram and open liver biopsy are the foundations of diagnostic evaluation. Percutaneous liver biopsy should be avoided. Failure to appreciate the possibility of hepatic angiosarcoma in the proper clinical setting, leading to blind percutaneous biopsy, may result in failure to make the diagnosis at the cost of significant morbidity and mortality. Survival of patients with hepatic angiosarcoma is brief; only 3% live longer than 2 years. Treatment of the tumor to date is empirical. There are probably a few patients who might benefit from radical surgery with curative intent. For all others chemotherapy is indicated. Adriamycin is active against hepatic angiosarcoma, but optimal dose and mode of administration require further investigation. Further study is also required to delineate the cause of hepatic angiosarcoma in the 60% of cases without definite epidemiologic association.  相似文献

Splenic tumors are very rare. In Japan only 42 cases of splenic angiosarcoma have been reported. We encountered a case of spontaneous rupture of a splenic angiosarcoma and liver metastasis. A 60-year-old woman who suddenly went into hemorrhagic shock presented at our hospital. Then acute spontaneously ruptured spleen and hepatic tumors were diagnosed by abdominal CT. After emergency TAE, the patient was hemodynamically stable, but died of liver failure 13 days after admission. The pathological diagnosis was primary splenic angiosarcoma with multiple organ metastasis on autopsy. Splenic angiosarcoma should be kept in mind in the differential diagnosis of splenomegaly or splenic tumor. TAE can be effective in primary hemostasis for angiosarcoma with intraperitoneal hemorrhage from multiple tumors.  相似文献
