目的探讨膈褶及其在肝表面所形成的肝副裂的超声声像图表现。方法连续观察2012年5月至2013年12月中南大学湘雅医院2037名腹部超声受检者，分析肝内出现膈褶受检者的临床资料和超声表现。结果2037名受检者中共15名检出膈褶，男性5名，女性10名，平均年龄（79.4±9.50）岁，不同性别受检者膈褶检出率差异无统计学意义（χ2=0.1382，P＞0.05）；50岁及以下受检者，无一名膈褶检出；50岁以上受检者，随着年龄的增长，膈褶检出率呈增加趋势，80岁及以上者共检出10名；伴有慢性阻塞性肺疾病（COPD）患者的膈褶检出率高于无COPD的受检者[5.49%（5/91） vs 0.91%（10/1091）]，且差异有统计学意义（χ2=29.5034，P=0.0000）。单发者12名，多发者3名，膈褶宽度均值为（9.48±2.47）mm，均位于肝右叶膈面且呈后上-前下走向。超声声像图长轴切面上表现为宽度基本一致的长条形稍强回声带，且回声强弱相间，呈“栅栏状”改变；短轴切面上表现为紧贴膈下的类圆形稍强回声团，内部回声强弱相间。结论膈褶及肝副裂相伴出现，其超声表现比较典型，易于发现但难以识别，其超声表现与一些肝内正常结构或病变相类似。
目的探討膈褶及其在肝錶麵所形成的肝副裂的超聲聲像圖錶現。方法連續觀察2012年5月至2013年12月中南大學湘雅醫院2037名腹部超聲受檢者，分析肝內齣現膈褶受檢者的臨床資料和超聲錶現。結果2037名受檢者中共15名檢齣膈褶，男性5名，女性10名，平均年齡（79.4±9.50）歲，不同性彆受檢者膈褶檢齣率差異無統計學意義（χ2=0.1382，P＞0.05）；50歲及以下受檢者，無一名膈褶檢齣；50歲以上受檢者，隨著年齡的增長，膈褶檢齣率呈增加趨勢，80歲及以上者共檢齣10名；伴有慢性阻塞性肺疾病（COPD）患者的膈褶檢齣率高于無COPD的受檢者[5.49%（5/91） vs 0.91%（10/1091）]，且差異有統計學意義（χ2=29.5034，P=0.0000）。單髮者12名，多髮者3名，膈褶寬度均值為（9.48±2.47）mm，均位于肝右葉膈麵且呈後上-前下走嚮。超聲聲像圖長軸切麵上錶現為寬度基本一緻的長條形稍彊迴聲帶，且迴聲彊弱相間，呈“柵欄狀”改變；短軸切麵上錶現為緊貼膈下的類圓形稍彊迴聲糰，內部迴聲彊弱相間。結論膈褶及肝副裂相伴齣現，其超聲錶現比較典型，易于髮現但難以識彆，其超聲錶現與一些肝內正常結構或病變相類似。

Objective To study the ultrasonic appearance of diaphragmatic muscular slips and accessory ifssures of liver. Methods The observations were based on 2 037 cases of abdominal sonography from May 2012 to December 2013 in Xiangya Hospital Center South University. The clinical data and ultrasonic appearances in patients with diaphragmatic muscular slips were retrospectively analyzed. Results Among the 2 037 cases, diaphragmatic muscular slips were found in 15 patients with a mean age of 79.4±9.5 years, including ten females and ifve males. The detection rate of diaphragmatic muscular slips showed no signiifcant gender predisposition (χ2=0.138 2, P>0.05). No diaphragmatic muscular slip was found in patient under 50 years old. And the diaphragmatic muscular slips detection rate increased with age increasing. Ten cases were found in patients above 80 years old. Moreover, the detection rate was signiifcantly higher in patients with concomitant chronic obstructive pulmonary diseases (COPD) than that without COPD [5.49%(5/91) vs 0.91%(10/1 091) (χ2=29.503 4, P=0.000 0). Diaphragmatic muscular slip was solitary in 12 cases and multiple in other 3 cases. The sulci had a mean width of 9.48±2.47 cm. All sulci were located in the superior surface of right lobe, radiating from diaphragmatic surface into the liver. In the long axis view, diaphragmatic muscular slip was a striated and slightly hyperechoic band with consistent width. In the short axis view, it was a round inhomogeneous hyperechogenecity close to the diaphragm. Conclusions Diaphragmatic muscular slip and the accessory ifssure were two ifndings usually accompanied with each other. Their appearances were typical and easy to detect. But the differentiation with normal and abnormal intrahepatic lesion was dififcult.
