Spinal meningoma

Case contributed by Dr Ian Bickle


Chronic back pain.

Patient Data

Age: 41 years
Gender: Male

1.3 cm well-circumscribed T1 and T2 isointense homogeneously enhancing intradural, extra-meduallary lesion at the origin of the filum terminale.

Minor displacement of the cauda roots, but no impingement.

The remainder of the spine is normal.

Case Discussion

A good fellowship examination case as:

  • Good for candidate to describe
  • Analyze the analytical skills to determine its anatomical origin
  • Provide a sensible differential
  • Probe as to which is the most likely pathology

Although ependymoma, schwannoma and neurofibroma are apt differential diagnoses, the signal characteristics are most fitting with a meningioma. This is the only one which is not typically hyperintense on the T2 sequences.

This was re-imaged 2 years later and was unchanged.
