Multiple glomus tumor on the anteromedial side of leg

Multiple glomus tumor is a rare benign neoplasm that arises from the glomus body in the stratum reticularis of the dermis, the highly specialized arteriovenous anastomosis for thermoregulation. Although several cases of multiple glomus tumor involving the anterior thigh, submandibular and parotid regions, the torso, have been reported, radiological characteristics on MRI images for multiple glomus tumor have not been described. We reported here both pre-operative and post-operative MR images from a case of 16 years old girl with multiple glomus tumor that partially coalesced on the anterior side of the leg. A 16-year-old patient was referred to our radiological department from the local clinic. The patient complained of the enlarging multiple masses on the anteromedial side of the leg that was found inadvertently 6 years ago. The pain was exacerbated during exercise. Clinical examination revealed 2 masses (3 cm 3 cm, 1.5 cm 1.5 cm) on the anteromedial side of the leg with mild tenderness and no ulceration. Routine laboratory tests showed normal results and no past medical or family history were informative. The patient underwent a 1.5T MR scan preoperatively and exhibited two well-defined lesions that partially
