Primary pulmonary meningioma may arise from meningothelial-like nodules

Abstract

A rare case of primary pulmonary meningioma, associated with meningothelial-like nodules in the same lung resection, with preoperative fine needle aspiration cytological findings and ultrastructural features, is described. The simultaneous presence of meningioma and meningothelial-like nodules, never before described, corroborates the unifying hypothesis of their common origin and nature.
