Abstract

This report describes the case of a 56 year-old man with a history of diplopia. His brain imaging showed multiple lesions with a metastatic appearance, however all investigations to determine the primary source of malignancy were negative. The patient underwent a brain biopsy, which was positive for anaplastic astrocytoma, a rare tumor that should be considered in the differential diagnosis of secondary brain tumors.
