Abstract:
Chest computed tomography (CT) findings of minute pulmonary meningothelial-like nodules (MPMNs) usually show tiny nodules (2-5 mm in diameter) of ground-glass attenuation. However, diffuse, thin-walled cavities have rarely been reported. We herein report a 56-year-old woman with MPMNs showing diffuse, thin-walled cystic lesions on a thin-section chest CT scan. Clinicians need to be aware of the imaging characteristics of this conditions to guide appropriate management of lung diseases, as these CT findings may resemble certain metastatic lung neoplasias and primary adenocarcinoma of the lung.
