【摘要】：目的:探討肝臟孤立性壞死結(jié)節(jié)(SNN)的MRI、CT表現(xiàn)及其鑒別診斷價(jià)值。方法:回顧性分析經(jīng)手術(shù)病理證實(shí)的47例SNN的臨床及影像學(xué)資料。38例行腹部MRI平掃及增強(qiáng)檢查,7例行腹部CT平掃及增強(qiáng)檢查,2例同時(shí)行MRI和CT檢查。結(jié)果:病灶位于肝右葉39例(39/47,83.0%),肝左葉8例(8/47,17.0%);分布于肝實(shí)質(zhì)邊緣42例(42/47,89.4%),肝臟深部5例(5/47,10.6%);病灶最大徑≤2.5cm者25例(25/47,53.2%)、2.5cm者22例(22/47,46.8%);形態(tài)不規(guī)則29例(29/47,61.7%),呈圓形或橢圓形18例(18/47,38.3%)。MRI示所有病灶于T1WI上呈低信號(hào)-等信號(hào),32例病灶T2WI上呈等信號(hào)-稍高信號(hào)、8例呈稍低信號(hào)。CT平掃示所有病灶內(nèi)部呈稍低-低密度影,1例病灶邊緣可見(jiàn)環(huán)形鈣化。三期增強(qiáng)掃描顯示所有病灶內(nèi)部無(wú)強(qiáng)化,周邊有薄環(huán)狀延遲強(qiáng)化,其中18例病灶內(nèi)間隔有輕度強(qiáng)化。結(jié)論:SNN的MRI、CT表現(xiàn)具有一定特征性,有助于該病的診斷。
[Abstract]:Objective: to investigate the CT findings of solitary necrotic nodule of liver (SNN) and its differential diagnostic value. Methods: clinical and imaging data of 47 cases of SNN proved by operation and pathology were retrospectively analyzed. 38 cases of abdominal MRI plain scan and contrast-enhanced examination were analyzed retrospectively. MRI and CT were performed in 2 cases. Results: 39 cases were located in the right lobe of the liver and 83.0% were located in the right lobe, 8 cases had 8 / 47 717.0% of the liver, 42 cases were located on the edge of the liver parenchyma, 5 cases were in the deep part of the liver, and 25 cases had the largest lesion diameter 鈮，
