A case of malignant hemangiopericytoma of the right ventricular outflow tract and the pulmonary artery associated with formation of a pseudoaneurysm in the latter is presented. This 33 year-old man had a four month history of illness. From the surgical point of view, all non-invasive modalities including phonocardiography, M-mode and two-dimensional echocardiography, radionuclide angiocardiography and contrast computed tomography underestimated the extent of the tumor as compared with the selective cineangiographic estimation. Therefore, it was suggested that in some situations where surgery is contemplated, a combination of non-invasive methods and cineangiography is essential to obtain sufficient diagnostic information, although the introduction of catheters into the right-sided cardiac chambers containing a mass might be hazardous because of potentiality dislodging portions of a tumor or adherent thrombus. Concerning pericardial abnormalities, contrast computed tomography was the most sensitive and specific method among the diagnostic techniques used in this case.
本文报告一例右心室流出道及肺动脉恶性血管外皮细胞瘤，并伴有后者假性动脉瘤形成。该33岁男性有4个月的病史。从手术角度来看，与选择性心血管造影评估相比，所有非侵入性检查方法，包括心音图、M型和二维超声心动图、放射性核素心血管造影和对比计算机断层扫描，都低估了肿瘤的范围。因此，有人提出，在考虑手术的某些情况下，尽管将导管插入含有肿块的右侧心腔可能因有使肿瘤部分或附着血栓脱落的风险而具有危险性，但将非侵入性方法与心血管造影相结合对于获得足够的诊断信息至关重要。关于心包异常，在本病例使用的诊断技术中，对比计算机断层扫描是最敏感和特异的方法。
