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. 18F-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.

摘要

黏膜相关淋巴组织（MALT）淋巴瘤起源于输尿管极为罕见。我们报告一例 55 岁女性，因右下腹疼痛 10 天就诊，18F-FDG PET/CT 发现右输尿管下段 MALT 淋巴瘤。超声显示右骨盆内低回声肿块，包绕右输尿管下段。18F-FDG PET/CT 显示肿块摄取 FDG 增高，同时腹腔内可见多个 FDG 摄取增高的肿大淋巴结。术后病理证实输尿管肿块为 MALT 淋巴瘤。
