Cranial and Spinal Meninges01:19

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...

Olfactory Receptors: Location and Structure

The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...
Cryptococcal Meningitis01:27

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,...
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...
Bacterial Meningitis I: Introduction01:22

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 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...

Summary

Olfactory groove meningiomas are slow-growing brain tumors. Surgical treatment outcomes and complications were analyzed in 29 patients, comparing results with existing literature.

Area of Science:

  • Neurosurgery
  • Oncology
  • Neuropathology

Background:

  • Meningiomas are typically benign intracranial tumors arising from arachnoidal cap cells.
  • Olfactory groove meningiomas specifically develop in the anterior cranial fossa.
  • These tumors often grow large asymptomatically, leading to delayed diagnosis and symptoms like visual defects and seizures.

Purpose of the Study:

  • To present and analyze surgical results and complications for olfactory groove meningiomas.
  • To compare findings with previously reported series in the literature.

Main Methods:

  • Retrospective analysis of 29 patients surgically treated for olfactory groove meningiomas.
  • Data collected between May 1992 and November 2003.
  • Evaluation of surgical outcomes and complications.

Main Results:

  • Detailed presentation of surgical outcomes for the cohort.
  • Analysis of complications encountered during surgical treatment.
  • Comparative analysis with existing studies on olfactory groove meningiomas.

Conclusions:

  • Surgical intervention is a primary treatment modality for olfactory groove meningiomas.
  • Understanding surgical outcomes and potential complications is crucial for patient management.
  • Further comparison with literature aids in refining surgical strategies.
