Abstract:
A 17-year-old female underwent metastasectomy of three synchronous lesions in the bilateral lungs under the diagnosis of metastatic osteosarcoma, however, one of them was found to be atypical adenomatous hyperplasia (AAH). Since AAH is very rare among young people, a careful evaluation of high-resolution computed tomographic image is important in determining the operative indications and procedures in patients with multiple metastatic tumors.
