Glomus tumor imaging: use of MRI for localization of occult lesions

Abstract

Magnetic resonance imaging has been performed in six patients with glomus tumors of the hand and correlated with clinical surgical histopathologic findings and with angiography in one case. Two of the patients had obscure pain without the classic clinical and radiologic findings of glomus tumors. The MRI examinations depicted the tumors in excellent detail and facilitated diagnosis in the two patients with atypical presentation. In all six cases the diagnoses were confirmed at surgery. The MRI proved valuable as a noninvasive and accurate means for the early diagnosis of occult glomus tumors.
