目的:探讨儿童腹部Burkitt淋巴瘤结外侵犯的MSCT表现及其诊断价值。方法:回顾性分析本院22例经病理证实的Burkitt淋巴瘤的腹部MSCT资料,对其结外病变进行分类和影像学表现分析。结果:Burkitt淋巴瘤可侵犯腹盆腔的多个结外脏器,包括腹部实质脏器(8/22)和胃肠道(21/22)。病变多表现为轻度强化的密度均匀的实性肿物,出血、坏死少见,钙化罕见;常伴肠系膜及腹膜后多个肿大淋巴结、大网膜广泛增厚或腹腔积液,以回肠远端浸润型和胰腺多发结节型最多见。结论:Burkitt淋巴瘤常同时侵犯腹盆腔多个结外脏器,儿童Burkitt淋巴瘤腹部结外侵犯的MSCT表现有一定特征性。
Objective: To investigate the clinical manifestations and diagnostic value of extracranial invasion of Burkitt’s lymphoma in children with abdomen. Methods: The abdominal MSCT data of 22 pathologically confirmed Burkitt’s lymphoma patients were retrospectively analyzed. Their extranodal lesions were classified and analyzed by imaging findings. Results: Burkitt lymphoma can invade multiple extranodular organs in the pelvic cavity, including the real abdominal organs (8/22) and the gastrointestinal tract (21/22). More lesions showed mild enhanced density of solid tumors, rare bleeding, necrosis, calcification rare; often accompanied by mesenteric and retroperitoneal multiple enlarged lymph nodes, omentum extensive thickening or ascites, to the ileum far Terminal infiltration and pancreatic multiple nodules most common. CONCLUSION: Burkitt’s lymphoma often invades multiple extranodal organs of the pelvic cavity at the same time. MSCT manifestations of extra-abdominal abdomen involvement in children with Burkitt’s lymphoma have certain characteristics.
