Opto-chiasmatic arachnoiditis in the young.

G Iraci, M A Gerosa, L Tomazzoli

    Child'S Brain
    |January 1, 1983
    PubMed
    Summary

    Surgery for opto-chiasmatic arachnoiditis in 14 young patients showed varied outcomes, with 5 experiencing functional improvement. Clinical data is crucial for diagnosis, as pneumoencephalograms can be misleading.

    Area of Science:

    • Neurosurgery
    • Ophthalmology
    • Neurology

    Background:

    • Opto-chiasmatic arachnoiditis is a rare condition affecting the optic pathways and chiasm.
    • Understanding its etiopathogenesis is key to effective treatment.

    Purpose of the Study:

    • To present surgical outcomes for opto-chiasmatic arachnoiditis.
    • To evaluate the diagnostic role of pneumoencephalography versus clinical presentation.

    Main Methods:

    • Retrospective analysis of 14 pediatric patients undergoing craniotomy for opto-chiasmatic arachnoiditis.
    • Surgical intervention involved lysis of adhesions.
    • Follow-up duration extended up to 23 years.

    Main Results:

    • Two main etiopathogenetic forms were identified.

    Related Experiment Videos

  • One postoperative death occurred in a patient with severe intracranial hypertension.
  • Positive surgical outcomes (functional improvement) were observed in 5 patients; others had indifferent or negative results.

    • Conclusions:

    • Craniotomy and lysis of adhesions offer potential benefits but with variable outcomes.
    • Clinical presentation is paramount in diagnosing opto-chiasmatic arachnoiditis.
    • A negative pneumoencephalogram does not exclude the diagnosis.
