Herpes simplex virus type 1 encephalitis and unusual retinitis in a patient with systemic lupus erythematosus.

In this report we discuss a case of a patient with systemic lupus erythematosus who developed herpes simplex virus type 1(HSV-1) infection presenting with encephalitis as well as necrotic and non-necrotic retinitis. The patient presented with typical clinical symptoms and radiologic abnormalities consistent with HSV-1 encephalitis and HSV-1 retinitis in patients with HIV infection, but lacked cerebrospinal fluid pleocytosis and had bilateral retinitis with poor visual acuity. To the best of our knowledge, this is the first such case reported in the literature.
