Cystic meningiomas present unique diagnostic challenges, often requiring MRI with gadolinium enhancement for accurate preoperative assessment. Complete surgical resection is the goal, with careful attention to cyst walls during surgery.

Area of Science:

  • Neurosurgery
  • Neuroradiology
  • Neuropathology

Background:

  • Cystic meningiomas are a subtype of meningioma with varied clinical presentations.
  • Understanding their distinct imaging features and pathological mechanisms is crucial for effective management.

Purpose of the Study:

  • To elucidate the clinical characteristics of cystic meningiomas.
  • To review diagnostic modalities and surgical considerations for cystic meningiomas.

Main Methods:

  • Retrospective analysis of 21 patients diagnosed with cystic meningiomas.
  • Literature review focusing on clinical presentation, imaging, diagnosis, surgical findings, and histopathology.
  • Classification of cysts as intratumoral or peritumoral using Nauta's method.

Main Results:

  • 14 intratumoral and 7 peritumoral cysts were identified in the patient cohort.
  • Computed tomography (CT) diagnosis can be challenging, with potential confusion with glioma or metastasis.
  • Magnetic resonance imaging (MRI) with gadolinium enhancement significantly improves diagnostic accuracy, revealing characteristic signal intensities and enhancing solid components.

Conclusions:

  • MRI with gadolinium enhancement is vital for accurate diagnosis and surgical planning of cystic meningiomas.
  • Total surgical resection is the preferred treatment, necessitating meticulous attention to the cyst walls.
