Ultrasonographic and FDG-PET imaging of the scrotal mass.
The ultrasonographic features of the scrotal mass [Fig. 1A] have been displayed in two images. There is a large hydrocele visualized, with nodular masses arising from the tunica vaginalis. The FDG-PET features of the mass [Fig. 1B] demonstrate a localized photopenic mass within the hemi-scrotum with high peripheral FDG-avid metabolic activity, with corresponding areas identified on CT [blue & red arrows].
