A well-corticated finger-like bony protuberance (pelvic digit) arising from the medial segment of right inferior pubic ramus extending laterally with pseudoarticulation with the medial aspect of neck of right femur.

Mild right hip effusion and synovial thickening with stranding of surrounding fat planes, reflecting synovitis.

Case Discussion

Pelvic digit is a rare congenital abnormality where there is development of bony tissue in the soft tissue pelvis and can be associated with pseudoarticulations. It is usually asymptomatic, however, in this case it can be the cause of associated synovitis.
