摘要
目的分析脾脏多发占位性病变多层螺旋CT、MR影像学表现特征。方法回顾性分析本院2017年6月至2019年7月收治的15例脾脏多发占位性病变患者的临床资料,观察脾脏多发占位性病变发生的部位、密度、形态、边界及增强扫描后强化方式和程度等;观察邻近组织器官的变化情况。结果MSCT示4例脾脏结核患者表现为脾脏内多发类圆形低密度灶,增强扫描后病灶呈环状强化。1例合并结核性腹膜炎,2例合并肝结核。脾脏淋巴瘤3例表现为弥漫性脾脏肿大,脾脏内浸润性结节影密度不均。脾门处及主动脉周围有成堆的肿大淋巴结。T_(1)WI表现为等或等低混合信号,T_(2)WI肿块信号略低于脾实质信号。脾脏脉管瘤中有2例可见出血坏死。T_(1)WI呈低信号,T_(2)WI呈高信号。结论MSCT检查和MRI检查均可有效显示脾脏多发占位性病变的影像学特点,但MRI检查鉴别诊断某些脾脏病变的能力要优于MSCT,可作为首选检查方式。
Objective To analyze the imaging features of multiple space occupying lesions of spleen in multislice spiral CT and MR.Methods The clinical data of 15 patients with multiple space occupying lesions of spleen admitted to our hospital from June 2017 to July 2019 were retrospectively analyzed.The location,density,shape,boundary and modes and extent of enhancement after enhanced scanning were observed.The changes of adjacent tissues and organs was observed.Results MSCT showed that 4 cases with tuberculosis of spleen showed multiple round-shaped low-density lesions in the spleen,and the lesions showed ring-like enhancement after enhanced scanning.One patient was combined with tuberculous peritonitis and two patients were combined with tuberculosis of liver.Three cases with spleen lymphoma showed diffuse splenomegaly and uneven density of infiltrating nodules in the spleen.There were piles of enlarged lymph nodes around the hilum of spleen and around the aorta.T_(1)WI showed equal or low and equal mixed signal,and the T_(2)WI mass signal was slightly lower than that of the spleen parenchyma.Hemorrhage and necrosis were seen in 2 cases with of the splenic angioma.T_(1)WI showed a low signal and T_(2)WI showed a high signal.Conclusion Both MSCT and MRI can effectively show the imaging features of multiple space-occupying lesions of spleen,but the ability of MRI to differentiate and diagnose some spleen lesions is better than MSCT,which can be used as the preferred method of examination.
