【摘要】：目的:报告并分析1例原发输尿管淋巴瘤的双时相正电子发射断层显像/计算机断层显像(positron emission tomography/X-ray computed tomography,PET-CT)表现,探讨PET-CT在该病诊断、分期及疗效监测中的价值。方法:回顾性分析1例原发输尿管淋巴瘤的临床及影像资料。结合文献,对其影像学表现,尤其是PET-CT表现及诊断价值进行探讨。结果:本例患者仅表现为镜下血尿,CT尿路造影示左输尿管中段肿块,输尿管镜示距膀胱入口5 cm处输尿管狭窄、未见肿块。手术活检确诊为输尿管滤泡性淋巴瘤。全身PET-CT显示为IE期。检索文献共收集资料齐全的原发输尿管淋巴瘤患者31例,发现输尿管淋巴瘤以单侧发生为主,临床表现不典型,病理类型以非霍奇金淋巴瘤为主,PET-CT检查伴有糖代谢增高。结论:原发输尿管淋巴瘤罕见,临床主要表现为胁痛、腹痛、无症状性肾积水,难以通过影像学手段正确诊断。PET-CT对于原发输尿管淋巴瘤临床分期、疗效监测、诊断有一定价值。
[Abstract]:Objective: to report and analyze 1 cases of primary ureteral lymphoma with double phase positron emission tomography / computed tomography (positron emission tomography/X-ray computed tomography, PET-CT), to investigate PET-CT in the diagnosis, staging and treatment monitoring value. Methods: a retrospective analysis of 1 cases of primary ureteral lymphoma: clinical and imaging data. Based on literature, their image features, especially the PET-CT manifestations and diagnostic value were discussed. Results: the patients only showed microscopic hematuria, CT urography showed the left ureter tumor, ureteroscopy showed from the bladder entrance 5 cm ureteral stenosis, withouttumor. Surgical biopsy diagnosed as ureteral follicular systemic lymphoma. PET-CT revealed stage IE. Literature retrieval complete information were collected from patients with primary lymphoma of ureter in 31 cases, lymphoma mainly unilateral ureter, The clinical manifestation and pathological type of non Hodgkin's lymphoma, sugar metabolism associated with PET-CT examination increased. Conclusion: primary ureteral lymphoma is rare, the main clinical manifestations of chest pain, abdominal pain, no symptoms of hydronephrosis, to the imaging methods for correct diagnosis of.PET-CT primary ureteral lymphoma clinical staging, treatment monitoring, diagnosis a certain value.
