Overview

There is no single diagnostic study of choice for the diagnosis of glomus tumor, but glomus tumors can be diagnosed based on MRI of the finger in addition to history and physical examination.

Diagnostic Study of Choice

Study of choice

• There is no single diagnostic study of choice for the diagnosis of glomus tumor, but glomus tumors can be diagnosed based on MRI of the finger in addition to history and physical examination.
• Glomus tumor is a vascular entity; hence it appears dark on T1 and bright on T2 weighted images.
• Post-gadolinium and fat saturation images help further delineate the benign tumor.
• Even though these findings can be seen with other vascular tumors, glomus tumor should be suspected due to the location at the digits and its small size.
