Abstract
Choriocarcinomas usually occur in the genital tracts of reproductive-age women after a gestational event. Primary pulmonary choriocarcinoma is very rare. We describe FDG PET/CT findings of primary pulmonary choriocarcinoma with multiple intrapulmonary metastases in a postmenopausal woman with elevated serum beta human chorionic gonadotropin level. On FDG PET/CT, the large primary lung tumor showed intense FDG uptake (SUV max , 46), and the small intrapulmonary metastases showed variable FDG uptake (SUV max , 27). Primary pulmonary choriocarcinoma should be included in the differential diagnosis of FDG-avid pulmonary lesions with elevated serum beta human chorionic gonadotropin levels, including metastatic choriocarcinoma and lung cancer.
