Herniation of the Colon Through Intercostal Space

A 55-year-old woman underwent two consecutive metastasectomy within four months due to left pulmonary metastases originated from a uterin leiomyosarcoma. Two months after the last operation she presented with a soft and lobulated mass just below her thoracotomy scar (Figure 1A-1B). Chest x-ray revealed subcutaneous air densities considered as a colon herniated through the 5th intercostal space and elevated diaphragm (Figure 1C-1D).
