肝脏继发性淋巴瘤的CT表现

CT image of liver secondary lymphoma

目的 探讨肝脏继发性淋巴瘤的CT表现,以提高对该病的认识和诊断能力. 方法 回顾性分析本院13例经肝穿刺病理学或者临床治疗证实的肝脏继发性淋巴瘤患者的资料,其中12例为非霍奇金淋巴瘤,1例霍奇金淋巴瘤.所有患者均行腹部CT扫描,其中11例行平扫＋增强扫描,2例仅平扫.结果 在13例肝脏继发性淋巴瘤中,结节（肿块）型11例,弥漫型1例,混合型1例.所有病变CT平扫均呈低密度影像;增强后,1例影像呈环状强化,1例轻至中度延迟强化,1例中度强化,2例轻度强化,以不均匀强化为主,其中3例出现＂血管漂浮征＂,6例无明显强化.结论 肝脏继发性淋巴瘤的CT表现主要为乏血供,增强扫描出现＂血管漂浮征＂对诊断有重大意义.

Objective To analyze the CT image characteristics of liver secondary lymphoma.Methods The medical records of 13 patients were reviewed. There were 12 non-Hodgkin lymphoma cases and 1 Hodgkin lymphoma case. Abdomen CT scan was performed in all cases, plain scan and enhanced CT scan were performed in 11 cases, plain CT scan was performed in 2 cases. Results Of the 13 cases, 11 were nodular type, 1 was diffuse type, and 1 was mixed type. Plain CT scan showed low density, enhanced CT showed circular enhancement in 1 case, mild to midrange delayed enhancement in 1 case, midrange enhancement in 1 case, mild enhancement in 2 cases, blood vessel floating sign in 3 cases, no enhancement in 6 cases.Conclusion The characteristics of liver secondary lymphoma CT image of liver secondary lymphoma includes blood vessel floating sign and enhancement.
