摘要
目的探讨小儿肝局灶性结节增生(FNH)的多层螺旋CT(MSCT)表现,加强对本病的认识,提高诊断准确率。方法选择2003年4月—2013年4月我院收治的经术后病理证实的小儿FNH患者10例,均行MSCT平扫及增强检查,分析其生长部位、大小、形态及血供特点。结果 10例患儿MSCT平扫时均呈等低密度,密度均匀或稍欠均匀,1例病灶内有成簇的砂粒状钙化。增强后动脉期,7例呈整体均匀强化,1例中心星芒状瘢痕区无强化,1例无强化的中心星芒区内示血管影,1例周边不均匀强化;静脉期病灶密度均略高于肝实质;延迟期均呈等密度。结论MSCT平扫与增强扫描能充分反映出病灶的血供特点及与周围肝组织的关系,对FNH做出正确诊断,降低误诊率。
Objective To discuss the multi - slice spiral computed tomography （MSCT） imaging manifestations of he- patic focal nodular hyperplasia （FNH） in children, to have better knowledge on this disease, and to improve its diagnostic accu- racy. Methods From April 2003 to April 2013, 10 children patients who were admitted to our hospital were diagnosed with FNH by postoperative pathology, they all received plain and enhanced MSCT scans, the location, size, morphology and blood supply of FNH were analysed. Results FNH plain MSCT scans of 10 children patients showed that the lesions were hypodense, homoge- neous or slightly less homogeneous, one lesion with clustered microealcifieations. The arterial phase enhanced MSCT scans showed that 7 lesions were homogeneously enhanced, one lesion＇s central scar area had no enhancement, artery shadow was found at the center scar area in one lesion without enhancement. One lesion＇s peripheral area was inhomogeneous enhanced. The portal phase enhanced MSCT scans showed that the density of lesions was a little higher than that of liver parenehyma. The delayed phase en- hanced MSCT scans showed all lesions were isodense. Conclusion Plain and enhanced MSCT scans can fully reflect the blood supplying of FNH and the relationship between lesion and the surrounding liver tissue, thus can make the right diagnosis and re- duce misdiagnosis rate.
