CNS toxoplasmosis, a rare presentation in a patient with Myasthenia Gravis.

ABSTRACT

We report the case of a 78-year-old man with a past medical history of non-Hodgkin's lymphoma s/p chemotherapy and Myasthenia Gravis on chronic mycophenolate mofetil (MMF), who presented with altered mental status and was found to have ring enhancing brain lesions. A brain biopsy revealed organisms consistent with Toxoplasma gondii. Cerebral toxoplasmosis has been rarely reported in patients with hematologic malignancies or in those receiving immunosuppressive agents. There needs to be a high degree of suspicion for T. gondii in HIV-negative individuals who are on immunosuppressants drugs including MMF.
