Summary
This study details an unusual suprasellar meningioma in a female patient causing vision loss. Surgery revealed an aberrant ophthalmic artery and optic nerve compression as key factors.
Area of Science:
- Neuro-oncology
- Ophthalmology
- Neurosurgery
Background:
- Suprasellar meningiomas are tumors in the brain region above the pituitary gland.
- Visual field defects are common symptoms, but this case presents unique causative factors.
Observation:
- A female patient presented with a right-sided inferior altitudinal visual field defect.
- Surgical exploration revealed the specific anatomical abnormalities contributing to the visual deficit.
Findings:
- An unusual suprasellar meningioma was diagnosed.
- Two primary causative factors were identified during surgery: an aberrant ophthalmic artery and significant optic nerve compression.
Implications:
- Highlights the importance of detailed surgical planning for suprasellar meningiomas.
- Underscores the potential for atypical vascular anatomy to influence tumor presentation and surgical approach.
- Contributes to understanding the complex relationship between intracranial tumors and visual pathway compromise.
