A 56-year-old female patient with a 0.4-cm solid nodule in the right upper lobe underwent CT-guided microcoil localization before video-assisted thoracoscopic surgery.Immediate frozen-resection histopathology revealed a reactive lymph node. Post-marking sagittal reconstruction CT revealed that the intrapulmonary part of the microcoil was adjacent to the nodule (arrow), and the proximal end of the microcoil was located within the chest wall.
