Factors Associated with Requesting Magnetic Resonance Imaging during the Management of Glomus Tumors

Background: The characteristic clinical presentation of glomus tumors and the low negative predictive value of themagnetic resonance imaging (MRI) raise the question whether MRI improves their management. Therefore, this studyaimed 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 andanalyzed retrospectively. Multivariable logistic regression analysis was used to evaluate the independent predictors ofan 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 anMRI during the management of a glomus tumor.Conclusion: The role of an MRI during the management of a glomus tumor is unclear. Orthopaedic surgeons aremore likely to request an MRI. Furthermore, visible lesions with characteristic symptoms probably do not benefitfrom MRI. However, it may help to be sure that the highest-quality MRI is used with the best possible coil for thefinger.Level of evidence: IV
