Summary
Meningiomas can cause optic neuropathy, delaying diagnosis. Targeted MRI of anterior visual pathways is crucial for identifying these tumors when symptoms are unresponsive to steroids.
Area of Science:
- Neuro-oncology
- Ophthalmology
- Neuroradiology
Background:
- Meningiomas are benign tumors of the meninges.
- Diagnosis can be incidental or symptomatic, often presenting with neurological or ophthalmological issues.
Observation:
- Five women (mean age 52) presented with progressive unilateral vision loss and visual field defects.
- Initial fundus examination was normal, and symptoms mimicked inflammatory central nervous system conditions.
Findings:
- Diagnosis of meningioma was delayed by 18 months to 4 years due to atypical presentation and initial misdiagnosis.
- Optic neuropathy unresponsive to steroids prompted re-evaluation and imaging.
- MRI findings (iso-intense on T1, slightly hyperintense on T2) can be subtle, requiring experienced interpretation.
Implications:
- Consider meningioma of the anterior visual pathways in cases of progressive optic neuropathy unresponsive to steroids.
- Targeted MRI with specific protocols (contrast, fat suppression, anterior pathway focus) is essential for accurate diagnosis and timely management.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
