Insights

Extracranial meningiomas are rare tumors affecting the paranasal sinuses. This study reviews three cases, highlighting diagnostic and treatment challenges for these unusual neoplasms.

Area of Science:

  • Neurology
  • Oncology
  • Otolaryngology

Background:

  • Extracranial meningiomas are uncommon, accounting for about 2% of all meningiomas.
  • These tumors typically arise within the skull but can occur in extracranial locations, such as the paranasal sinuses.

Observation:

  • A retrospective review identified three patients with meningiomas involving the frontal, ethmoid, and sphenoid sinuses over 25 years.
  • Presenting symptoms included facial pain, nasal obstruction, and facial swelling.
  • Diagnosis was confirmed through endoscopic transnasal biopsy in two patients and CT-guided biopsy in one.

Findings:

  • Surgical removal was successful for tumors in the ethmoid and frontal sinuses.
  • The patient with a sphenoid sinus meningioma received radiation therapy.
  • Extracranial meningiomas of the paranasal sinuses pose diagnostic and therapeutic challenges.

Implications:

  • Early diagnosis and tailored treatment are crucial for managing these rare tumors.
  • This case series contributes to understanding the clinical presentation and management of sinonasal meningiomas.
  • Further research is needed to optimize treatment strategies for extracranial meningiomas in this location.

Cranial 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...
Bacterial Meningitis01:24

Bacterial Meningitis

Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
Viral Meningitis01:18

Viral 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...

Cryptococcal 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,...

Bacterial 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...
Bacterial Meningitis II: Pathophysiology01:26

Bacterial 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...
