The migration was discovered three years post-insertion during a routine replacement visit. Despite the absence of pulmonary symptoms, a CT scan revealed the implant in the inferior lobe of the right lung. The patient was referred for further evaluation, but immediate surgical removal was deferred. This case report highlights the importance of healthcare providers recognising migration as a rare complication during implantation and suggests self-examination as a potential preventive strategy.
