Abstract
A transthoracic fine-needle aspiration biopsy, sampled under echographic guidance from a pleuro-pulmonary mass, proved to be a metastatic meningioma. The meningioma had been operated on from the left parietal lobe, twelve years previously. Cytologic specimens showed nests of round-to-spindle-shaped tumor cells with whorl formation; the cells were immunoreactive for vimentin and epithelial-membrane antigen. The cytological appearance of the tumor cells was diagnostic of meningioma. In the course of the clinical staging, a recurrent cerebral meningioma was found and was judged to be inoperable, because of extensive growth and brain infiltration.
