Glomus tumor is a benign tumor that originates in the glomus, which is an arterio-venous shunt involved in body temperature regulation. Glomus tumor is typically characterized with triad: intermittent pain, tenderness and the pain is reproduced when the lesion is placed in the cold water. Most glomus tumors are benign. On MR imaging glomus tumor is isointense on T1- and hyper-intense on T2-weighted images, with homogenous enhancement after contrast.
