Abstract

Abstract: Mucosa-associated lymphoid tissue (MALT) lymphoma origin from the ureter is exceedingly rare. We report FDG PET/CT findings of MALT lymphoma in the distal right ureter in a 55-year-old woman who presented right abdominal pain for 10 days. Ultrasound revealed a hypoechoic mass in the right pelvis, which was surrounding the distal right ureter. 18 F-FDG PET/CT demonstrated a high FDG uptake by the mass along with several FDG-avid enlarged lymph nodes in the abdominal cavity. Postoperative pathology demonstrated the ureteral mass as a MALT lymphoma.
