Types of glomus tumors of the nail bed

TypeFeatures
Vascularcontains numerous vascular lumens. Enhancement very high post Gadolinium with high T2 signal. Early enhancement in angiography with increase in delayed venous phase
Cellularproliferation of epitheloid cells, less vascular lumens. Difficult to detect in scans. Gadolinium does not help much. 3D GRE imaging may show a peripheral capsule, or slight bone erosion of distal phalanx
Mucoidmucoid degeneration of stroma, mild enhancement post Gado. Very high T2 signal due to large amount of water in stroma
