Primary pulmonary meningiomas are rare and their occurrence has been reported only sporadically. The diagnosis of such tumors should be accepted only after the presence of an intracranial or intraspinal meningioma has been excluded. The morphological and immunohistochemical features are similar to those of intracranial meningiomas. A case of primary pulmonary meningioma along with a review of the literature and discussion of other lesions in the differential diagnosis of this rare neoplasm are here presented.
