Opto-chiasmatic arachnoiditis in the young
Child'S Brain
|January 1, 1983
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.
- 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.
