【摘要】 目的探讨微泡型多囊肝超声诊断与超声分型的价值。方法回顾性分析17例微泡型多囊肝的超声表现及相关临床资料,并与MR影像进行对照印证。结果 17例微泡型多囊肝超声诊断符合12例,诊断符合率70.59%(12/17);误诊5例,占29.41%(5/17)。MR诊断符合率100%(17/17)。微泡型多囊肝均表现为肝实质非均匀性回声增强,呈粗大点条状、等号状或斑片状、筛网状非均匀分布;部分病例除以上改变外,还显示有单个或散在分布的几个毫米级的典型囊肿回声;依据异常回声的肝实质内有否超声可显示的典型囊肿,而将其分为Ⅰ型(经典型)、Ⅱ型(非经典型)两类。本组Ⅰ型7例;Ⅱ型10例。结论超声对微泡型多囊肝的准确诊断虽不及MR敏感、可靠,但他具有MR不具备的诸多优势,因此,仍是本病诊断与鉴别诊断的重要而首选的检查方法。更多还原

【Abstract】 Objective To explore the value of ultrasound in diagnosis and classification of micro-alveolar polycystic liver.Methods Ultrasonic features and correlated clinical data of 17 cases with micro-alveolar polycystic liver were analyzed retrospectively.All those cases were confirmed by magnetic resonance(MR) imaging.Results 12 cases were correctly diagnosed by ultrasound among those 17 cases and the diagnose accordance rate was 70.59%(12/17).Five cases(29.41%)were misdiagnosed.The diagnose accordance rate of MR was 100%。All those cases showed liver parenchyma echo heterogeneously enhanced,presented as gross punctiform,equal sign or patching,grit shape which distributed heterogeneously.Besides those features described above,some cases provided signal or several typical cysts whose diameter was less than 1 cm.According to if there was typical cyst in ultrasonic imaging,micro-alveolar polycystic liver cases were classified intoⅠgroup(typical group,no typical cyst )andⅡgroup(untypical group).In those 17 cases,7 cases were typical and 10 cases were untypical.Conclusions The diagnose accordance rate of ultrasound in diagnosis of micro-alveolar polycystic liver was inferior of that of MR,but ultrasound also had its own advantage and should be taken as a preferred method for diagnosis and differential diagnosis.更多还原
