Meningiomas of Meckel's cave
Journal of Neurosurgery
|August 1, 1975
Summary
Meningiomas in Meckel's cave present in three distinct clinical groups based on symptoms and prognosis. Early detection and removal of impinging masses offer the best outcomes for trigeminal neuralgia.
Area of Science:
- Neurosurgery
- Neurology
- Oncology
Background:
- Meningiomas of Meckel's cave can affect the Gasserian ganglion and trigeminal nerve.
- These tumors present a diagnostic and therapeutic challenge due to their location.
Purpose of the Study:
- To classify clinical presentations of Meckel's cave meningiomas.
- To correlate clinical groups with prognosis and tumor characteristics.
Main Methods:
- Retrospective review of 12 Meckel's cave meningioma cases over 20 years.
- Analysis of clinical symptoms, neurological deficits, and histopathological findings.
Main Results:
- Group 1: Typical trigeminal neuralgia, easily removable mass, excellent prognosis.
- Group 2: Atypical facial pain, meningioma en plaque, poorer pain relief prognosis.
- Group 3: Dysesthesias, sensory loss, multiple cranial nerve deficits, aggressive histology, poor prognosis, and recurrence.
Conclusions:
- Meckel's cave meningiomas exhibit distinct clinical patterns.
- Prognosis and treatment outcomes vary significantly between clinical groups.
- Histological features correlate with tumor aggressiveness and patient outcomes.

01:19Cranial and Spinal Meninges
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...

01:18Viral Meningitis
Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
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,...
01:22Bacterial 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...
01:26Bacterial 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...
01:22Cerebral Edema ll: Pathophysiology
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
