Summary
This case report details a rare chordoid meningioma causing compressive optic neuropathy. Prompt diagnosis and treatment are crucial due to the tumor's aggressive nature and recurrence risk.
Area of Science:
- Neuro-oncology
- Ophthalmology
- Neuropathology
Background:
- Meningiomas are common intracranial and intraorbital tumors.
- Compressive optic neuropathy suggests a mass lesion impacting vision.
- Chordoid meningiomas are a rare subtype with aggressive potential.
Observation:
- A 51-year-old woman presented with symptoms of compressive optic neuropathy and orbital apex syndrome.
- Radiologic and neuropathologic findings revealed an atypical meningioma with chordoid features and frontal edema.
- Treatment involved orbitozygomatic craniotomy and radiotherapy.
Findings:
- The patient experienced significant postoperative improvement in visual and oculomotor function.
- A high MIB-1 labeling index (5-7%) indicates a potential for recurrence.
- This is the first reported case of an anterior temporal chordoid meningioma presenting as compressive optic neuropathy.
Implications:
- Chordoid meningiomas require prompt diagnosis and aggressive management due to their aggressive behavior.
- Early intervention is vital to mitigate morbidity from mass effect and reduce recurrence risk.
- This case underscores the importance of considering rare meningioma subtypes in optic neuropathy evaluations.

01:10The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

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...
01:27Cryptococcal Meningitis
Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
01:26Bacterial Meningitis II: Pathophysiology
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
01:22Bacterial Meningitis I: Introduction
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
