本研究的目的是评估局限性肺粘液性细支气管肺泡癌（BAC）的薄层计算机断层扫描（CT）和氟脱氧葡萄糖正电子发射断层扫描（FDG-PET）表现。2000年2月至2009年2月，有7例手术标本中经病理证实的肺局限性粘液性BAC患者。对他们的 CT 结果进行了评估，包括毛玻璃混浊 (GGO) 的位置、范围（百分比）、边缘特征以及含空气空间和收缩变化的存在。我们评估了接受增强 CT 的患者是否存在“血管造影征象”。测量4例FDG-PET最大标准化摄取值(SUVmax)。所有肿瘤均位于下叶。 GGO 的百分比范围从 0% 到 70%（平均 20%）。 5 例肿瘤边缘界限清楚，2 例肿瘤边缘界限不清。在所有情况下都观察到含有空气的空间。七个案例中有两个出现了收缩变化的证据。接受增强 CT 扫描的五名患者中的一名发现了血管造影征象。 FDG-PET 的 SUVmax 范围为 0.93 至 1.97（平均 1.53）。局部粘液性 BAC 的影像学特征包括实性或部分实性衰减、存在含空气空间、缺乏收缩性变化和下叶优势。此外，FDG-PET 的 SUVmax 明显较低。
The aim of this study was to evaluate thinsection computed tomography (CT) and fluorodeoxyglucose positron emission tomography (FDG-PET) findings of localized pulmonary mucinous bronchioloalveolar carcinomas (BACs).From February 2000 to February 2009, there were seven patients with pulmonary localized mucinous BACs that were pathologically confirmed in the surgical specimens. Their CT findings were assessed regarding location, extent (percent) of groundglass opacity (GGO), margin characteristics, and the presence of air-containing spaces and contractive changes. We evaluated the presence of the "angiogram sign" in the patients who underwent enhanced CT. The maximum standardized uptake value (SUVmax) on FDG-PET was measured in four cases.All tumors were located in the lower lobes. The percentages of GGOs ranged from 0% to 70% (average 20%). The tumor margins were well defined in five cases and ill-defined in two cases. Air-containing spaces were seen in all cases. Evidence of contractive change was seen in two of the seven cases. The angiogram sign was identified in one of five patients who underwent enhanced CT. The SUVmax on FDG-PET ranged from 0.93 to 1.97 (mean 1.53).The imaging features of localized mucinous BACs include solid or partly solid attenuation, the presence of air-containing spaces, lack of contractive changes, and lower lobe predominance. Additionally, the SUVmax is markedly low on FDG-PET.
