The M-mode and 2-D echocardiographic features of an unusual case of a "pseudo-tumor" of the right ventricular outflow tract are reported. The unique pathologic findings of the pulmonary valve with congenital fenestrations and the clinical implications of this "pseudo-tumor" are discussed. Whenever calcification is noted at fluoroscopy to exist in a region or structure being evaluated by echocardiography, caution must be taken to avoid overestimating the size. Indistinct, dense reflectances without specific motion or appearance of a mass further helps to distinguish the reflectances from an actual structure of significance. Furthermore, all clinical, angiographic, and echocardiographic information must be interpreted together when either the angiogram or the echocardiogram is confusing and potentially misleading.
报告了一例右心室流出道“假性肿瘤”的罕见病例的M型和二维超声心动图特征。讨论了具有先天性开窗的肺动脉瓣的独特病理发现以及这种“假性肿瘤”的临床意义。每当在荧光透视下注意到钙化存在于超声心动图评估的区域或结构中时，必须小心避免高估其大小。无特定运动或肿块外观的不清晰、密集反射进一步有助于将这些反射与具有重要意义的实际结构区分开来。此外，当血管造影或超声心动图令人困惑且可能产生误导时，所有临床、血管造影和超声心动图信息都必须综合解读。
