Cerebral Toxoplasmosis in Systemic Lupus Erythematosus

A 37-year-old man with underlying systemic lupus erythematosus and lupus nephritis presented with an episode of generalized tonic seizure. He complained of poor concentration and forgetfulness for 1 week. He suffered a relapse of lupus nephritis 4 months ago and received a course of intravenous methylprednisolone followed by oral prednisolone and mycophenolate mofetil. Clinically, there was no focal neurological deficit. Retroviral screening was negative. Magnetic resonance imaging (MRI) of the brain revealed eccentric and concentric signs which confirmed the diagnosis of cerebral toxoplasmosis.
