Pelvic digit (also known as a pelvic rib or pelvic finger) is a rare congenital abnormality where there is development of bony tissue in the soft tissue pelvis (and less commonly in the abdomen). They can be associated with one or more pseudo-articulation. They are usually unilateral.
Treatment and prognosis
It is a benign entity and if incidentally discovered no further investigation is required.
