CTICasesPericardial Herniation Post-Surgery (Two Examples)
Imaging findings
Two examples were presented. In one post-operative case, a significant portion of the heart was herniated into the right hemithorax through a pericardial defect. In another post-pneumonectomy case, a smaller protrusion of the heart, specifically the right atrial appendage, was visible through a defect, consistent with the "snow cone sign."
Key takeaways
These cases demonstrate different presentations of pericardial herniation of the heart through surgical pericardial defects, ranging from extensive herniation to more localized protrusion (the "snow cone sign"), illustrating this rare but important post-surgical complication.
