title: Usefulness of F-18 fluorodeoxyglucose positron emission tomography/computed tomography in a case of choriocarcinoma presenting as pulmonary embolism.
abstract: This case demonstrates the utility of performing F-18 fluorodeoxyglucose positron emission tomography/computed tomography for the investigation of an unresolving pulmonary embolus, where early diagnosis of tumor thrombus or primary neoplastic conditions of the pulmonary artery may be made. Choriocarcinoma presenting within the pulmonary artery is rare although a literature review shows that a number of important differential diagnoses of hypermetabolic pulmonary lesions should be kept in mind.
