Imaging findings
High-resolution computed tomography of the chest reveals multiple tiny, sub-centimeter, bilateral ground-glass nodules predominantly distributed in the lower lung zones. Some of these tiny nodules demonstrate subtle central lucencies suggestive of microcavitation on thin-section CT.
Key takeaways
Minute pulmonary meningothelial-like nodules are benign interstitial cell nests commonly found incidentally in resected lung specimens or on high-resolution chest CT during staging. They typically present as tiny, stable, bilateral ground-glass nodules, sometimes with microcavitation, and should not be mistaken for atypical adenomatous hyperplasia or metastatic disease.
