Multifocal glioblastoma with liver metastases in the absence of surgery

Abstract

✓ A patient with two intracerebral glioblastomas of differing histology with metastases to the liver in the absence of surgery is reported. The gliomatous nature of the lesions was confirmed by staining for glial fibrillary acidic protein. Histological and immunohistochemical evidence suggests that the metastases arose from the more poorly differentiated of the intracerebral tumors. One of the intracerebral tumors had enhanced expression of the ras p21 oncogene as compared to the other tumors and as compared to nonmalignant brain tissue from this patient.
