Optic neuritis and computed tomography

F M Booth, J Hallinan

    Australian Journal of Ophthalmology
    |November 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    A patient experienced unilateral vision loss and optic disc swelling, initially suspected to be an optic nerve tumor. Symptoms resolved spontaneously, and follow-up imaging confirmed a normal optic nerve.

    Area of Science:

    • Ophthalmology
    • Neurology
    • Radiology

    Background:

    • Optic nerve tumors present with visual disturbances and disc edema.
    • Computed Tomography (CT) is a key imaging modality for orbital pathology.

    Observation:

    • A 40-year-old male presented with acute unilateral visual loss and optic disc edema.
    • Orbital CT revealed diffuse thickening and tortuosity of the optic nerve, suggestive of a tumor.

    Findings:

    • The patient reported subjective visual improvement, leading to the deferral of surgical intervention.
    • A subsequent CT scan two months later showed a normal-appearing optic nerve, resolving the initial findings.

    Implications:

    • This case highlights the possibility of spontaneous resolution of optic nerve abnormalities initially suspected to be tumors.

  • It underscores the importance of clinical correlation and serial imaging in managing optic nerve disorders.
  • The differential diagnosis for optic nerve thickening should include inflammatory or transient conditions.
