A well-defined oval-shaped enhancing lesion measuring 8 x 8 x 12 mm is seen along the posterior aspect of the right internal mammary artery which is likely a pseudoaneurysm. A mildly hyperdense non-enhancing soft tissue is seen around it which is likely a localised haematoma. Small right pleural effusion with atelectatic changes in the right lower lobe.
Impression: Iatrogenic right internal mammary artery pseudoaneurysm with a surrounding haematoma.
