Ureteral metastasis from an appendiceal carcinoma and diagnosis by endoscopic ultrasound-guided fine-needle aspiration.
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.
