摘要
目的分析肝脏泡状棘球蚴病CTMRI表现,评价CTMRI对肝包虫病的诊断价值。方法回顾分析15例经CTMRI诊断及手术病理证实的肝包虫病影像学资料。结果15例共发现肝包虫囊肿17个。CT表现边界清晰或稍模糊的圆形或椭圆形不均匀密度减低区;大部分病灶可见钙化。MRI表现在T1加权像上边界清晰或稍模糊的圆形或椭圆形不均匀的低信号影,其内散在分布不规则的更低信号影。在T2加权像上,病灶呈不均匀高信号。病灶内的钙化在T1和T2加权像上呈条状、点状、斑片状无信号区(钙化)。增强扫描强化不明显。结论CTMRI对肝包虫病有较高的诊断价值。
[Objective] To discuss the CT and MRI features of liver alverlar hydatid diseases. [ Methods] CT and MRI characteristics in fifteen patients admitted to our hospital and diagnosed as liver alverlar hydatid diseases were retrospectively analyzed. [Results] 15 lesions had 17 cysts. CT appeared roundness or ellipse asymmetry density cyst walls of lesions with calcification. MRI appeared roundness or ellipse asymmetry singal cyst walls, T1WI appeared low singal; T2WI appeared high singal, calcification of lesions appeared no singnal. Cyst walls were not enhanced. [Conclusion] CT and MRI had much more value in evaluating location and qulity of liver alverlar hydatid diseases.
