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

Abstract

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