Gestational Trophoblastic Disease with Pulmonary and Cerebral Metastasis: Can Fluorodeoxyglucose Positron Emission Tomography Really Detect Cranial Metastatic Disease ?

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 evaluation 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.

Akciğer ve Beyin Metastazlı Gestasyonel Trofoblastik Hastalık: Pozitron Emisyon Tomografisi Kranial Metastatik Hastalığı Saptayabiliyor mu?

Abstract

Gestasyonel Trofoblastik Neoplaziler (GTN) plasenta dokusundan köken alırlar ve erken vasküler invazyon yaptıklarından sıklıkla metastaz yaparlar. Beyin metastazı nadir görülür. Metastatik GTN’nin taranmasında 18-florodeoksiglukoz pozitron emisyon tomografisinin (FDG-PET) etkinliği konusunda veriler yetersizdir. Bu olgu sunumunda, eş zamanlı akciğer ve beyin metastazı olan ve beyin metastazının FDG-PET ile saptanamadığı bir GTN olgusunu sunuyoruz.
