Presentation
Painful swelling of the 2nd finger of the left hand.
Patient Data
Cortical scalloping of the medial aspect of the distal phalanx.
A well-defined homogeneous hypoechoic soft tissue mass of the medial aspect of the distal phalanx with prominent internal vascularity on color Doppler.
The MRI sequences demonstrate a small well-defined soft tissue mass (7 x 6 x 5 mm) on the medial aspect of the distal 2nd digit with cortical scalloping. It elicits a low signal on T1, high signal on T2 fat saturation with vivid and homogeneous enhancement on postcontrast sequences.
Case Discussion
MRI features are most consistent with a glomus tumor
Glomangiomas, also known as glomus tumors, are benign vascular tumors typically seen at the distal extremities. On imaging, they characteristically present as small hypervascular nodules under the fingernail.
