Optic nerve cysticercosis, a rare condition, involves a parasitic cyst within the optic nerve. Medical treatment with albendazole and steroids effectively resolved the cyst, preserving vision.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Neuroscience

Background:

  • Cysticercosis, a parasitic infection caused by the larval cysts of the tapeworm Taenia solium, can affect various organs, including the central nervous system.
  • Optic nerve cysticercosis is an exceedingly rare manifestation, with limited documented cases in medical literature.

Observation:

  • A 25-year-old female presented with recurrent episodes of visual decline, ocular pain, and proptosis.
  • Diagnostic imaging, including computed tomography and ultrasonography, identified an intraneural cyst containing a scolex within the retrobulbar segment of the optic nerve.
  • Serological testing via enzyme-linked immunosorbent assay confirmed the presence of cysticercosis.

Findings:

  • The study reports a rare case of cysticercosis affecting the optic nerve.

  • Medical management utilizing oral albendazole and corticosteroids led to complete resolution of the intraneural cyst.
  • The patient experienced minimal residual visual impairment following treatment.

    • Implications:

    • This case highlights the importance of considering cysticercosis in the differential diagnosis of optic nerve pathologies, even in its rare presentations.
    • Effective medical treatment can lead to favorable outcomes, preventing severe visual loss.
    • Further research into the pathogenesis and optimal management of neurocysticercosis affecting the optic nerve is warranted.
