Meningioma of Lung: First Report with Light and Electron Microscopic Findings

Abstract

This is the first report of a primary meningioma of the lung. The lesion was present at least 4 years prior to its operative removal. The 59-year-old patient is still healthy 2 1/2 years after operation. All examinations, including computed tomography, failed to detect another primary tumor. Light and electron microscopic findings are identical to those in endotheliomatous meningioma. The relations to the so-called minute pulmonary chemodectomas and the probable histogenesis are discussed.
