Localized collection of fluid in an interlobar fissure as a consequence of congestive heart failure is a well-known entity. It has been termed vanishing tumor because of its appearance as a mass lesion in the lung and its propensity to resolve with diuretic therapy. We report a case of loculated pleural effusion in the subcostal pleural space without interlobar fluid collection. This was initially thought to represent an occult metastatic malignancy; however, the cause of the density became obvious when it disappeared with therapy of heart failure and recurred concurrent with cardiac decompensation. Loculated pleural effusion must be included in the differential diagnosis of roentgenographic densities in the chest when seen in subcostal as well as in interlobar locations.
因充血性心力衰竭导致叶间裂局部积液是一种众所周知的情况。它被称为“消失性肿瘤”，因为其在肺部表现为肿块样病变，且有经利尿治疗后消退的倾向。我们报告一例肋下胸膜腔局限性胸腔积液病例，无叶间积液。该病例最初被认为是隐匿性转移性恶性肿瘤；然而，当积液经心力衰竭治疗后消失，并在心脏失代偿时复发，其密度改变的原因就变得明显了。当在肋下及叶间部位出现局限性胸腔积液时，在胸部X线密度的鉴别诊断中必须考虑到这种情况。
