Pelvic digit

[edit] Discussion

Rare congenital anomaly where bone tissue develops in soft tissue.
It can be located at any level of the pelvic bones or even in the anterior abdominal wall
Asymptomatic benign entity which is usually discovered incidentally.
Recognition of this benign anomaly is important to avoid unnecessary clinical investigations or even interventions.
Radiological differentiation from heterotopic ossification (post-traumatic myositis ossificans) and avulsion fractures of the pelvis can usually be made because of the typical appearance of the pelvic digit and the absence of a history of trauma.
