Presentation
Small painful nodule of the 1st finger of the left hand.
Patient Data
Small well-defined homogeneous hypoechoic nodule of the dorsal aspect of the distal phalanx with prominent internal vascularity on SMI (superb microvascular imaging).
Small well-defined soft tissue mass measuring 6 x 5 x 4 mm on the dorsal aspect of the distal phalanx 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
The location and the MRI features are most consistent of a glomus tumor, also known as glomangioma.
Glomus tumors are benign vascular tumors typically seen at the distal extremities. On imaging, they characteristically present as small hypervascular nodules under the fingernail.
