Acquired immunodeficiency syndrome associated with cerebral astrocytoma.

A 32-year-old homosexual man presented with headache and progressive right hemiparesis. CT scan revealed a heterogeneous ring-enhancing mass in the left parietooccipital lobe which proved to be astrocytoma. Clinicians should be aware of this new and unusual association of a cerebral glioma and acquired immune deficiency syndrome. Tissue examination is essential for proper diagnosis.
