Minute pulmonary meningothelial-like nodules (MPMNs) are benign small lesions in the lungs, with similar pathological characteristics to the meningeal epithelium. MPMNs have similar imaging manifestations to malignant tumors, which can lead to misdiagnosis in clinical practice. There is no consensus on the pathogenesis of MPMNs, with some suggest that MPMNs derive from reactive proliferation, while others suggest that MPMNs share a common origin and molecular mechanism with meningiomas in the central nervous system. Understanding the characteristics of MPMNs and studying their pathogenesis will help improve the understanding and diagnosis of MPMNs. In this article, we reviewed the clinical, pathological, imaging characteristics, differential diagnosis and pathogenesis of MPMNs. We also analyze the existing research advances regarding the pathogenesis and propose prospects for further research. .
【中文题目:肺微小脑膜上皮样结节——认知进展与争论】 【中文摘要:肺微小脑膜上皮样结节(minute pulmonary meningothelial-like nodules, MPMNs)是一种与脑膜上皮有相似病理学特征的肺部良性小病灶,和恶性肿瘤有相似的影像学表现,可在临床上导致误诊。关于MPMNs的发病机制尚未达成共识,有观点认为MPMNs可能是一种反应性增生,也有观点认为MPMNs与中枢神经系统脑膜瘤有共同的起源和分子机制。了解MPMNs的特征,深入研究其发病机制,有助于提高对该病的认识和诊断水平。本文就MPMNs的临床、病理、影像学特点以及鉴别诊断和发病机制进行综述,并全面分析了其发病机制的研究进展,对进一步探索提出展望。 】 【中文关键词:肺微小脑膜上皮样结节;脑膜瘤;肺肿瘤;多原发肺癌】.
