title: [The contribution of MRI in the study of glomus tumors].
abstract: The glomus tumors of the finger tip are benign. Their diagnosis is clinic but their precise localization is quite difficult by classic imaging. MRI with gadolinium injection seemed a good method to check exactly this lesion and have been tested on 20 patients suspected suffering of glomus tumor. On 18 glomus tumors surgically and histologically confirmed MRI examination have been positive for 16. In two cases MRI and surgery were negative. A good correlation seems observed with surgery for the size (7 tumor of 2 mm) the localization and osseus extension. Addition of T2 and T1 before and after injection weighted acquisitions improved the results. Precise informations on topography and size seems improved the surgical approach.
