Aseptic meningitis and herpes simplex proctitis. A case report

Insights

Herpes simplex virus type 2 (HSV-2) can cause aseptic meningitis in homosexual men with anal herpes. This sexually transmitted infection requires consideration in meningitis diagnoses.

Area of Science:

  • Virology
  • Neurology
  • Infectious Diseases

Background:

  • Aseptic meningitis is an inflammation of the membranes surrounding the brain and spinal cord.
  • Herpes simplex virus type 2 (HSV-2) is a common cause of genital herpes.
  • HSV-2 infections are typically associated with genital lesions.

Observation:

  • A homosexual male patient presented with acute ano-proctitis.
  • The patient subsequently developed symptoms of aseptic meningitis.
  • Herpes simplex virus type 2 (HSV-2) was identified as the causative agent for both conditions.

Findings:

  • This case demonstrates a link between HSV-2 ano-proctitis and aseptic meningitis.
  • Aseptic meningitis due to HSV-2 has been previously associated with genital herpes, but not typically with anal herpes.
  • The findings highlight a potential neurological complication of anal HSV-2 infection.

Implications:

  • Healthcare providers should consider HSV-2 in the differential diagnosis of aseptic meningitis, particularly in patients with a history of or risk factors for sexually transmitted infections.
  • This case expands the known clinical spectrum of HSV-2 neurological complications.
  • Further research may be warranted to understand the incidence and mechanisms of HSV-2-associated meningitis from anal infections.
