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.
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
- T1 images
- 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.[1]
