The authors report two cases of pseudomesotheliomatous lung cancer (PLC) detected by (18)F-FDG PET/CT scan. (18)F-FDG PET/CT clearly revealed the extent of the disease in both cases, a case of adenocarcinoma of the lung and a case of squamous cell carcinoma of the lung. Intense (18)F-FDG uptake by the diffusely thickened pleurae and primary lesion was observed in both cases, and increased (18)F-FDG uptake by a pelvic bone metastasis was observed in the case of squamous cell carcinoma. Although PLC is indistinguishable from malignant pleural mesothelioma on (18)F-FDG PET/CT scans, (18)F-FDG PET/CT was helpful in identifying the primary focus of the PLCs and in staging the disease. Diagnostic image interpreters should be familiar with the (18)F-FDG PET/CT findings in PLC.
作者报告了两例通过（18）F-FDG PET/CT 扫描检测到的假间皮瘤性肺癌（PLC）。（18）F-FDG PET/CT 在这两例中均清晰地显示了疾病的范围，一例为肺腺癌，一例为肺鳞癌。在这两例中，弥漫性增厚的胸膜和原发性病变均观察到强烈的（18）F-FDG 摄取，在肺鳞癌的病例中还观察到骨盆骨转移的（18）F-FDG 摄取增加。尽管在（18）F-FDG PET/CT 扫描上 PLC 与恶性胸膜间皮瘤无法区分，但（18）F-FDG PET/CT 有助于识别 PLC 的原发灶并进行分期。诊断图像解读员应熟悉 PLC 的（18）F-FDG PET/CT 表现。
