Endoscopic ultrasound (EUS) is a standard tool for imaging the gastrointestinal tract
and adjacent structures. EUS-guided fine-needle aspiration (FNA) allows the endosonographer
easy access to these structures for both diagnostic and therapeutic purposes. We describe
a case of metastatic lesion, adherent to a stented right ureter, which was imaged
with transrectal EUS, with successful cytologic identification after EUS-guided FNA.
EUS and EUS-guided FNA can be valuable tools in the evaluation of some soft-tissue
abnormalities of the pelvis.
