摘　　要：目的：研究脂肪肝患者胆囊床附近肝岛的发生率及临床意义。方法：搜集经超声诊断为脂肪肝的患者5／13例，其中男310例，女233例，年龄13～69岁，平均45．6岁。由同一超声科医生对所有患者进行腹部脏器常规超声检查，重点扫查胆囊床处肝组织。结果：81．9％的脂肪肝患者胆囊床处出现肝岛，轻度脂肪肝患者与中～重度脂肪肝患者胆囊床处肝岛的发生率分别为81．2％、87．1％，脂肪肝严重程度与肝岛的发生率无相关性（x2值为1．464，P值为0．226）。男性脂肪肝患者与女性脂肪肝患者胆囊床处肝岛发生率分别为83．5％、79．8％，性别与肝岛的发生率无相关性（x2值为1．245，P值为0．265）。结论：弥漫性脂肪肝患者胆囊床附近肝岛具有较高的发生率，在与肝内占位性病变及胆囊病变侵及肝脏的鉴别诊断中应予以考虑。Objective：To assess the incidence of focal spared areas around bed of gall baldder in hepatic steatosis. Methods：543 patients were diagnosed hepatic steatosis on ultrasound including 310 male and 233 female. Mean age was 45. 6 years （range, 13~69 years）. All patients underwent routine ultrasound examination by the same sonographer. More atten tion was paid to areas around bed of gall bladder. Results：The incidence of focal spared areas around bed of gall bladder in patients with hepatic steatosis was 81.9%. The incidence was 81.2% and 87. 1% in patients with mild hepatic steatosis and moderate severe hepatic steatosis respectively. The incidence was 83.5% and 79.8% for men and women in patients with hepatic steatosis respectively. No correlation was found between degree of hepatic steatosis （P=0. 226） and gender （P =0. 265 ）. Conclusion：There exists high incidence of focal spared areas around bed of gall bladder in hepatic steatosis. These focal sapred areas should be considered in the differential diagnosis of primary or secondary lesions of liver.
