摘要
目的 分析原发性肝脏淋巴瘤的CT、MRI影像学特点及其临床诊断价值。方法 回顾分析本院2010年1月至2019年5月收治的13例PHL患者的临床资料,所有患者均接受MSCT、MRI检查。对患者所得影像图片进行分析,以病理活检为基准,对比CT、MRI检查对PHL检出正确率。结果 CT检查对PHL检出正确率为53.84%,MRI正确率为76.92%,两者比较差异无统计学意义(P>0.05)。CT平扫:病变均为低密度,且密度均匀,边界清楚;增强扫描:可见动脉期病灶无明显强化,门脉期为轻度强化。MRI图像可见,T1WI呈稍低或明显低信号,T2WI则为稍高信号,DWI为特征性高信号。肿块中心有坏死者T2WI为中度或明显高信号。1例患者为轻度强化,并有“血管漂浮”征出现。CT及MRI检查增强后多为轻度强化。结论 PHL为罕见疾病,影像学表现缺乏特异性,CT、MRI检查中显示其为乏血管肿瘤,增强扫描多为轻度强化表现,CT、MRI检查对其有一定诊断价值,但确诊仍需依靠穿刺活检或病理检查等。
Objective To analyze the CT and MRI imaging features of primary hepatic lymphoma and their clinical diagnostic value. Methods The clinical data of 13 patients with PHL admitted to our hospital from January 2010 to May 2019 were retrospectively analyzed. All patients underwent Ms CT and MRI. The images obtained from the patients were analyzed, and the accuracy of CT and MRI for detection of PHL was compared. Results The accuracy of CT examination for PHL was 53.84%, and the accuracy of MRI was 76.92%. There was no significant difference between them(P>0.05). CT plain scan: lesions are low density, uniform density, and the border is clear. Enhanced scan: in the arterial phase, the lesion did not significantly strengthen, and in the portal phase, the lesion was mildly enhanced. MRI images showed that T1WI showed slightly lower or significantly lower signal, T2WI was slightly higher signal, and DWI was characteristic high signal. T2WI of patients with necrosis in the center of the mass was moderate or significantly high signal. One patient has mild enhancement and has“vascular floating sign”. After enhancement, CT and MRI examinations main showed mild enhancement. Conclusion PHL is a rare disease, and its imaging lacks specificity. CT and MRI showed that it was a hypovascular tumor, and the enhanced scan shows mostly mildly enhancement. CT and MRI have some diagnostic value, but the diagnosis depends on needle biopsy or pathological examination.
