Overview

MRI is helpful in the diagnosis of glomus tumor. Findings on MRI suggestive of glomus tumor includes hyperintense signal on T2 and PD (proton-density) weighted imaging.[1]

MRI

  • MRI may be helpful in the diagnosis of glomus tumor. Findings on MRI suggestive of glomus tumor include:
    • 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.
    • 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.
  • It can also be useful for assessment of patients with recurrence or incomplete resolution of symptoms following surgery.
