RT Journal Article SR Electronic T1 [18F]FDG PET/CT in Metastatic Extragonadal Choriocarcinoma JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol.

Inconclusive biopsies due to a high necrotic component often delay diagnosis. Here is such a case, in which suggestive imaging findings on [18F]FDG PET/CT, a raised level of serum β-human chorionic gonadotropin, and gynecomastia clinched the diagnosis.
