[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.
