Loculation of a pleural effusion within an interlobar fissure as a result of congestive heart failure is a well-known entity. It has been termed "vanishing" or "phantom" tumor because its roentgenographic appearance simulates a pulmonary tumor and resolves with treatment of the congestive heart failure. The authors describe an 89-year-old man with a loculated pericardial effusion on the left cardiac border on chest roentgenogram. This was initially thought to represent an occult metastatic malignancy; however, its etiology became obvious when it disappeared with therapy of heart failure. Loculated pericardial effusion should be included in the differential diagnosis of roentgenographic densities in the chest when seen on the left cardiac border.
因充血性心力衰竭导致的叶间裂内胸腔积液包裹是一种众所周知的情况。它被称为“消失性”或“幻影”肿瘤，因为其X线表现类似肺部肿瘤，且随着充血性心力衰竭的治疗而消退。作者描述了一名89岁男性，胸部X线片显示左心缘有包裹性心包积液。最初认为这代表隐匿性转移性恶性肿瘤；然而，当它随着心力衰竭的治疗而消失时，其病因变得明显。当在左心缘看到胸部X线密度影时，包裹性心包积液应列入鉴别诊断。
