(a) Axial STIR image demonstrating a small cluster of vessels in the subcutaneous tissue overlying the palmar aspect of the second metacarpal head, measuring 7 × 9 mm (solid arrow). No involvement of the underlying musculature; (b) coronal MIP image of dynamic MRA (TWIST) at the level of the lesion demonstrating no enhancement in the early arterial phase or arterial feeders (outline by the white circle); (c) axial ASL showing normal signal intensity in the region of interest (outline by the white circle). ASL, arterial spin labeling; MIP, maximum image projection; MRA, MR angiography; STIR, short tau inversion recovery.
