Imaging findings
Following a lobectomy in March 2013, a new focal opacity was observed within the left pulmonary artery on a follow-up CT in July 2013. This opacity remained unchanged in subsequent CT examinations over many months. A PET scan performed in November of the same year showed no FDG activity associated with the lesion.
Key takeaways
This case illustrates focal thrombosis, commonly referred to as stump thrombosis, which can occur in the pulmonary artery following a lobectomy or pneumonectomy. It is crucial to recognize this as a benign, non-metabolically active post-surgical finding to differentiate it from recurrent tumor or other pathological processes. The stability of the lesion over time and lack of FDG avidity on PET are key features in its characterization.
