Twenty-one hepatic Echinococcus granulosus cysts (maximal diameter, 7.5 cm +/- 4.0) in 12 patients were aspirated and irrigated with hypertonic (20%) saline under sonographic guidance. All patients had signs and symptoms of a hepatic mass caused by the cysts, which had a prominent fluid component that appeared anechoic or hypoechoic, with marked enhancement of back wall echoes. The amounts of cyst fluid aspirated and of hypertonic saline used were 190 mL +/- 240 and 120 mL +/- 90, respectively. Separation of the endocyst from the pericyst and nonviability of scoleces were observed in all cysts. Mean hospital stay was 4.0 days +/- 3.4. Serial sonographic examinations revealed high-level echoes in the cyst cavity (heterogeneous echo pattern), which ultimately became uniformly echogenic (pseudotumor). After follow-up of 14.0 months +/- 5.5, maximal cyst diameter decreased to 4.1 cm +/- 3.1 (P less than .001). One patient died of unrelated causes; the remaining 11 patients experienced relief of symptoms and a decrease in liver span.
在超声引导下，对12例患者的21个肝细粒棘球蚴囊肿（最大直径7.5 cm±4.0）进行了穿刺抽吸并用高渗（20%）盐水冲洗。所有患者均有囊肿引起的肝脏肿块的体征和症状，囊肿有明显的液性成分，表现为无回声或低回声，后壁回声明显增强。抽吸的囊液量和使用的高渗盐水量分别为190 mL±240和120 mL±90。在所有囊肿中均观察到内囊与外囊分离以及头节无活力。平均住院时间为4.0天±3.4。系列超声检查显示囊肿腔内有高回声（不均匀回声模式），最终变为均匀回声（假瘤）。经过14.0个月±5.5的随访，囊肿最大直径降至4.1 cm±3.1（P<0.001）。1例患者死于无关原因；其余11例患者症状缓解，肝径缩小。
