Mass: A palpable cyst or solid mass would generally be easily seen on ultrasound or MRI. Pathologic adenopathy is also readily seen. So the two most likely possibilities would be a normal lymph node that is superficial enough to feel, or a benign lipoma, which is a soft fatty tumor that may have a capsule so thin it can be indistinguishable from adjacent normal fat on imaging. Talk to your doc.
