Abstract

Insights

This study analyzed 90 operated meningioma cases, finding they are more common in females and often located in the para-sagittal region. MRI signal intensity did not correlate with tumor grade.

Area of Science:

  • Neurosurgery
  • Neuropathology
  • Radiology

Background:

  • Meningiomas are the most common primary intracranial tumors.
  • Understanding their epidemiological and radiological characteristics is crucial for diagnosis and management.

Purpose of the Study:

  • To report the experience with operated meningioma cases at Jordan University Hospital.
  • To analyze prevalence, location, and clinical presentation.
  • To investigate the correlation between MRI signal intensity and histological grades for radio-pathological diagnosis.

Main Methods:

  • Retrospective review of 90 operated meningioma cases from January 1997 to January 2007.
  • Analysis of medical records, histopathological reports, and neuroimages.
  • Evaluation of tumor characteristics including location, multiplicity, and MRI signal intensity.

Main Results:

  • Meningioma prevalence was higher in females (2.2:1 ratio).
  • Para-sagittal meningiomas were most common (23.3%).
  • Most tumors were benign, showing iso-intense signals on T1/T2 and hyper-intense signals on FLAIR with vivid enhancement.

Conclusions:

  • Findings on gender prevalence and anatomical location align with global literature.
  • No significant correlation was found between MRI signal intensities (T1WI, T2WI, FLAIR) or enhancement patterns and histological grades.

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

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...
