Presentation
Abdominal pain. No prior medical or surgical history.
Patient Data
Osseous linear structure divided into three segments joined by pseudo-articulations within left abdominal wall soft tissue, arising from the level of pubic symphysis, representing a pelvic/abdominal digit.
Right paraumbilical hernia containing loops of bowel.
Infrarenal IVC filter in situ.
Case Discussion
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.
