Diagnosis and retreatment of a tumor recurrence previously treated by image-guided percutaneous pulmonary RFA. a–c Appearance of a solid nodular lesion adjacent to an ablative area in the radiologic control performed six months after a percutaneous lung RFA to treat lung metastasis from a rectal carcinoma (arrow). This lesion exhibits avid FDG (b) and iodine contrast (c) uptake (arrows), and it is consistent with a tumor recurrence at the ablation site. d The lesion is re-treated using percutaneous lung MWA, with a central consolidative area (arrow) surrounded by a ground-glass halo of more than 5 mm (triangle). These findings are consistent with comprehensive treatment
