Minute pulmonary meningothelial-like nodules are often incidentally discovered during pathologic evaluation of pulmonary parenchymal specimens. These lesions were once thought to represent pulmonary chemodectomas, but pathological studies have shown that they are not of neuroendocrine origin. Minute pulmonary meningothelial-like nodules are benign, perhaps reactive in nature, but are occasionally found in association with lung carcinoma. They may appear as randomly distributed well-defined micronodules on thin-section chest CT, and thus may simulate metastatic disease when associated with lung carcinoma.
微小肺脑膜上皮样结节常在肺实质标本的病理评估中偶然发现。这些病变曾被认为是肺化学感受器瘤，但病理研究表明它们并非神经内分泌起源。微小肺脑膜上皮样结节是良性的，可能本质上是反应性的，但偶尔会与肺癌相关。它们在胸部薄层CT上可能表现为随机分布的边界清晰的微小结节，因此与肺癌相关时可能会模拟转移性疾病。
