Bilateral papillitis as the initial presentation of neurosyphilis in a patient previously treated for primary and secondary syphilis

PURPOSE: To report a patient previously treated for primary and secondary syphilis who presented with papillitis. The patient was found to have neurosyphilis likely due to inadequate treatment of primary and secondary syphilis. OBSERVATIONS: A 60-year-old male with human immunodeficiency virus (HIV) and hepatitis C was referred for evaluation of blurry vision for the past several months. Anterior segment examination was notable for 1+ diffuse non-granulomatous keratic precipitates and 2+ flare with trace cell in both eyes. Dilated fundus exam revealed grade 2 optic disc edema in both eyes with no evidence of infectious retinitis. He was recently treated for syphilis with a single dose of intramuscular (IM) penicillin. These findings were consistent with syphilitic papillitis likely secondary to neurosyphilis. The patient underwent a lumbar puncture which confirmed the diagnosis of neurosyphilis. He was admitted to the hospital for intravenous (IV) penicillin. He later revealed a prior history of syphilis that was treated 3 years ago and 1 year ago. CONCLUSIONS AND IMPORTANCE: Ocular syphilis can have a wide variety of presentations. Any patient with syphilis and uveitis should have prompt work up for neurosyphilis. Patients with any stage of syphilis need close follow up with repeat titers after treatment to ensure adequate treatment and prevent progression and permanent ocular or neurologic sequelae.
