Pelvic/abdominal digit (a.k.a. 11th finger) is a rare abnormality in which osseous tissue forms usually linear structures within pelvic or abdominal soft tissues. It is thought to be formed during embryogenesis from non-fusion of the vertebral column with the superior coccygeal bone. It is of no clinical significance, and usually an incidental finding.
