Three cases of cerebral lymphoma in patients with acquired immunodeficiency syndrome is presented. They are remarkable for their extremely rapid progression, which simulated an infectious processes during trials of antitoxoplasma therapy. Fourteen days of therapy are generally required to assess a negative response. However, earlier biopsies and shorter therapeutic trials may be indicated in these patients.

Case ReportsPleomorphic xanthoastrocytoma presenting with massive intracranial hemorrhage.
A 46-year-old woman presented with massive left temporal lobe intraparenchymal and diffuse subarachnoid hemorrhage on CT. Lack of enhancement excluded intermediate and high-grade primary tumor or metastasis as likely causes. At surgery, a fibrovascular left temporal lobe mass adherent to the dura proved to be a pleomorphic xanthoastrocytoma. The unusual hemorrhagic presentation of this typically benign entity is thought to be related to the meningeal involvement, which itself is characteristic of this neoplasm.
