Efficacy of CT‐guided localization followed by video‐assisted thoracoscopic surgery in children with tiny pulmonary nodules
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.
