ABSTRACT

Gestational trophoblastic neoplasms (GTN) originate from placental tissue and usually metastasizes because of its propensity for early vascular invasion. Intracranial metastases are relatively uncommon. There are limited data on the efficacy of 18-fluorodeoxyglucose positron emission tomography (FDG-PET) in the eva-luation of metastatic GTN. We present a case of GTN with simultaneous pulmonary and cranial metastases in which the cranial metasteses were undetectable with positron emission tomography (PET) scan.
