Overview

An MRI may be helpful in the diagnosis of glomus tumor. Findings on MRI suggestive of glomus tumor include slightly hypointense or hyperintense T1 images and hyperintense T2 images.

MRI

  • MRI may be helpful in the diagnosis of glomus tumor. Findings on MRI suggestive of glomus tumor include:[1]
    • T1 images
      • Slightly hypointense or hyperintense
    • T2 images
      • Hyperintense
  • Depending on the histologic subtype, diagnosis of glomus tumor may be more difficult and the signal can sometimes appear similar to the nail bed.[1]
    • The T1 image appears much more intense following gadolinium injection, allowing the lesion to be visualized more clearly.
  • The technique can be particularly useful for the detection of early lesions, which are very small (even 2 mm lesions) and difficult to diagnose either by physical examination or using other imaging techniques.[1]
  • It can also be useful for assessment of patients with recurrence or incomplete resolution of symptoms following surgery.[2]
