Imaging findings
Subtle extra opacity projected over the left hemidiaphragm on chest radiograph. On CT, an intermediate attenuation soft tissue lesion in the left anterior diaphragm, growing through a new iatrogenic diaphragmatic defect, contiguous with extensive similar soft tissue masses in the abdomen. A new surgical clip near the defect indicates recent surgery. Prior studies showed an intact diaphragm.
Key takeaways
Recurrent abdominal liposarcoma can extend into the mediastinum through an iatrogenic diaphragmatic defect, which may be a complication of prior debulking surgery. Correlating imaging findings with surgical history and recognizing new surgical changes (like clips) are essential for diagnosis.
