We present the case of a 64-year-old woman with a history of breast cancer who underwent explantation of a dysfunctional intravenous port system. At surgery a broken port catheter was found. A port catheter fragment embolized into the segmental artery of the posterobasal segment of the right inferior lobe, causing a wedge-shaped segmental perfusion defect in the corresponding segment. The catheter was removed by catheter intervention with a goose-neck snare.
