Dehiscent manubrium post CABG surgery with lung herniation

Case contributed by Chris O'Donnell


CABG surgery many years ago. Now has chest pain and cough. CT scan of the chest to assess for malignancy.

Patient Data

Age: 90 years old
Gender: Male

Ununited manubrial osteotomy (sternal split) with wire sutures that have "pulled through". Sternal body has united. Note how the lung (arrow) has herniated into the defect created by the non-union.

Case Discussion

This is an unusual non-union of the manubrium that has created a gap into which the lung has herniated and is presumably associated with a cough impulse.
