    Dear Editors

    While I have not doubt there are incidents involving vascular migration of Implanon NXT, the presentation of this case study raises some interesting questions verging to concerns about the details:

    1. As stated by the authors, the device measures 4 cm long and 2 mm diameters. The suggested radioopaque foreign body shown in Figure 1 and 2 appears to be disproportionately long. These images suggest the skeletal frame involving torso of the woman is no wider than 25-30 cm (bone-wise) which meant this is an extra-ordinarily small woman.

    2. CT Chest reported ‘hyperdense image with 40 mm, compatible with Implanon in the anterior basal segment of the lower left lobe in intravascular topography'. Interestingly the authors stated that "Implanon was removed by video assisted thoracoscopic surgery without pulmonary resection. Surgical procedure and postoperative course had no complications. " As reader may be aware, video assisted thoracoscopic surgery (VATS) primarily involved the insertion of thoracoscopes into pleural cavities via small incision on the chest. It would have been helpful to know if the implanon device had been found in the pulmonary vasculature, lung tissue or actually in the pleural space itself. As reflected in the article's own reference (1) on an example of VATS retrieval, it is no simple matter.

    The lack of such details in the article raises more questions than answers
