We are aware of seven previous case reports in the literature describing multiple primary brain tumors in the same patient.1-5 Few of these cases have been diagnosed during life, although one has been described in which both a meningioma and an adjacent oligodendroglioma were successfully removed at the time of a single operation.4 In the case we are about to describe, two primary brain tumors occurred in the same patient but only one of them was diagnosed at the time of operation. The fact that the remaining tumor occurred in the opposite hemisphere made the diagnosis somewhat more difficult, and it was only at autopsy that we obtained evidence of another primary brain tumor. Although this type of double lesion is very infrequent, our purpose in reporting these tumors is not only to add another case of considerable rarity to the literature but also to stress the possibility
