中文摘要:
      目的 探讨原发性胃淋巴瘤的CT表现特征。方法 回顾性分析经病理确诊的21例原发性胃淋巴瘤患者的CT表现,观察病变部位、范围、胃壁厚度、强化程度、胃腔、黏膜及浆膜改变特征、胃周淋巴结及其他器官侵犯特点。结果 本组21例原发性胃淋巴瘤患者均为非霍奇金淋巴瘤;19例为多发病灶,2例为单发病灶。CT表现为胃壁不均匀增厚(8 ~62 mm),其中弥漫性增厚10例,节段性增厚9例,局限性增厚2例;19例呈均匀强化,2例内见片状低密度坏死;12例胃壁黏膜线完整,9例黏膜破坏;胃壁浆膜面模糊2例,浆膜面清晰19例;12例胃腔无明显狭窄;6例胃周淋巴结肿大,未发现肝脏侵犯。结论 原发性胃淋巴瘤的CT表现具有一定的特征性;多排螺旋CT对诊断和鉴别诊断具有重要临床意义。
英文摘要:
      Objective To observe the multi-detector spiral CT manifestations of primary gastric lymphoma. Methods Multi-detector spiral CT findings of 21 patients with pathologically confirmed primary gastric lymphoma were retrospectively analyzed, the lesions’ site, extent, thickness of gastric wall, the enhancement pattern, the situation of gastral cavity and gastric mucosa, and the encroachment of perigastric lymph nodes and other organs were observed. Results Tumors in all 21 patients were non-Hodgkin lymphoma. Multiple lesions were found in 19 patients, while single lesion was detected in 2 patients. CT demonstrated irregular thickening of the gastric wall (8—62 mm) in all 21 patients, including diffuse thickening (n=10), segmental thickening (n=9) and local thickening (n=2). Homogeneous enhancements were found in 19 patients, and lamellar inhomogeneous necrosis were found in 2 patients. Intact mucosal lines were found in 12, and destructed mucosal line in 9 patients, while obscure serous membranes were found in 2, and distinct serous membrane in 19 patients. The stomach showed distensible without significant narrow in 12 patients. The enlargement of perigastric lymph nodes were found in 6 patients. No hepatic encroachment was found. Conclusion Multi-detector spiral CT manifestations of primary gastric lymphoma are relatively specific, and multi-detector spiral CT shows high value for the diagnosis of the disease.
