title: Malignant carcinoid tumor metastatic to a meningioma.
abstract: Postmortem examination in a patient with a widely disseminated pulmonary carcinoid tumor revealed invasion of a fibroblastic meningioma by metastatic tumor cells. To the authors' knowledge, this case represents the first example of a malignant carcinoid tumor that has metastasized to a primary intracranial neoplasm. The literature concerning metastasis of extracranial to primary intracranial tumors is briefly reviewed.
