Minute pulmonary meningothelial-like nodules: high-resolution computed tomography and pathologic correlations

J Thorac Imaging. 2002 Jul;17(3):227-9. doi: 10.1097/00005382-200207000-00008.

Abstract

Minute pulmonary meningothelial-like nodules (MPMNs), previously known as minute pulmonary chemodectomas, are relatively rare lesions. They are small (1-3 mm) and often multiple. Pathologically, they represent an interstitial nodular proliferation of small oval or spindle-shape cells arranged in a "zellenballen" nesting pattern. The function and origin of the cells are unknown. These nodules are associated with specific conditions, including thromboembolism, cardiac disease, and malignancy. We describe a patient with MPMNs and adenocarcinoma of the lung in whom HRCT showed tiny (1-3 mm in diameter) nodules of ground-glass attenuation.
