Primary central nervous system lymphoma is a rare brain tumor,
primarily seen in immunocompromised patients (e.g., AIDS, organ
transplantation). Patients present with headaches, seizures, or
focal neurological deficits. The tumor can involve the deep white
matter, the meninges, and the eye. If it involves the deep white matter, it may
spread across the corpus callosum, similar to the pattern seen
in glioblastoma multiforme. |
