Abstract

Background: The characteristic clinical presentation of glomus tumors and the low negative predictive value of the
magnetic resonance imaging (MRI) raise the question whether MRI improves their management. Therefore, this study
aimed to investigate whether MRI improved the management of glomus tumors.
Methods: In total, 87 patients with a histologically confirmed glomus tumor were treated over a 25-year period and
analyzed retrospectively. Multivariable logistic regression analysis was used to evaluate the independent predictors of
an MRI request during the management of glomus tumors.
Results: According to the results, the patients who were treated by orthopaedic surgeons were more likely to have an
MRI during the management of a glomus tumor.
Conclusion: The role of an MRI during the management of a glomus tumor is unclear. Orthopaedic surgeons are
more likely to request an MRI. Furthermore, visible lesions with characteristic symptoms probably do not benefit
from MRI. However, it may help to be sure that the highest-quality MRI is used with the best possible coil for the
finger.
