title: Efficacy of CT-guided localization followed by video-assisted thoracoscopic surgery in children with tiny pulmonary nodules.
abstract: CT-guided localization followed by video-assisted thoracoscopic surgery was performed in three children with pulmonary nodules less than 5 mm in diameter. The patients' respective primary diagnoses were Wilms tumor, hepatoblastoma, and osteosarcoma of the femur. The pulmonary nodules were marked preoperatively by a percutaneously placed hook-wire or dye under CT guidance. Although none of the nodules was grossly detected during the operation, they were correctly resected under the guidance of the hook-wire wound or dye. A histological assessment revealed viable metastatic lesions in the case of hepatoblastoma, completely necrotic lesions in the case of Wilms tumor, and inflammatory nodules in the case of osteosarcoma. CT-guided localization followed by video-assisted thoracoscopic surgery appears to be a beneficial procedure in children with tiny pulmonary nodules.
