Calcified acoustic neuroma.

R R Beskin1, J J Eick

  • 1Department of Radiology, Ochsner Clinic, New Orleans, La 70121.

Southern Medical Journal

Summary

Calcification can occur in acoustic neuromas, although it is uncommon. Magnetic resonance imaging (MRI) may improve preoperative diagnosis by differentiating acoustic neuromas from meningiomas based on signal characteristics.

Area of Science:

  • Neurology
  • Radiology
  • Oncology

Background:

  • Acoustic neuromas and meningiomas are both primary tumors of the cerebellopontine angle.
  • Preoperative differentiation between these tumors can be challenging.

Observation:

  • A case of acoustic neuroma with calcification is presented, highlighting an unusual finding.
  • Acoustic neuromas and meningiomas exhibit different signal characteristics on magnetic resonance imaging (MRI).

Findings:

  • Calcification is an infrequent but documented occurrence in acoustic neuromas.
  • MRI signal characteristics show a statistical tendency to differ between acoustic neuromas and meningiomas.

Implications:

  • Recognizing the possibility of calcification in acoustic neuromas is crucial for accurate diagnosis.
  • MRI can enhance the specificity of preoperative diagnosis for cerebellopontine angle tumors.
  • Improved preoperative diagnostic accuracy can guide surgical planning and patient management.
