Phantom tumors are accumulations of pleural effusion in the interlobular spaces of the lungs. They appear in patients with heart failure simulating a lung tumor but disappearing with medical treatment. The encystment of the fluid is apparently due to congenital defects in the pleura, which tends to store up the transudate produced by heart failure. Another pathogenetic possibility is the existence of pleural adherences. The most common localization is in the minor cissure, perhaps because it is more easily identified in the posterior view of the chest X-ray. In most of these cases the pleural effusion is due to left heart failure, though pleural effusion in normally associated with right congestive heart failure. On the posterior chest X-ray the fluid is observed as a round or fusiform mass. Differential diagnosis should be established for measotheliomas, pulmonary infarctions, pulmonary or metastatic tumoral nodules, hydatic cysts, and tuberculomas. Sixteen cases of phantom tumors are reported; nine of them were localized on the minor cissure, five on the right major cissure, one on the left major cissure, and one case of double localization on the left major cissure and minor cissure. All of them were due to left congestive heart failure.
假性肿瘤是肺小叶间隙内胸腔积液的积聚。它们出现在心力衰竭患者中，形似肺部肿瘤，但经药物治疗后会消失。液体的包裹显然是由于胸膜的先天性缺陷，这种缺陷倾向于储存心力衰竭产生的漏出液。另一种发病机制的可能性是存在胸膜粘连。最常见的部位是小裂，这可能是因为在胸部X线后前位片上更容易识别。在大多数此类病例中，胸腔积液是由左心衰竭引起的，尽管胸腔积液通常与右心充血性心力衰竭有关。在后前位胸部X线片上，液体表现为圆形或梭形肿块。应与间皮瘤、肺梗死、肺部或转移性肿瘤结节、包虫囊肿和结核瘤进行鉴别诊断。报告了16例假性肿瘤病例；其中9例位于小裂，5例位于右主裂，1例位于左主裂，1例为左主裂和小裂双发。所有病例均由左心充血性心力衰竭引起。
