目的复习经手术病理证实的肝包虫囊肿胆瘘的病例,提高对肝包虫囊肿胆瘘的认识。方法对22例经手术证实肝包虫囊肿胆瘘的CT病例进行了回顾性的分析。结果22例肝包虫囊肿胆瘘者CT均见囊肿张力变小,形态不规则,内囊破裂明显19例。分别见显示为“新月征”“囊中囊征”及“飘带样影”。2例虽未见内囊破裂,胆囊内见散在的不规则气体影。1例囊壁局部略增后,囊内密度明显高于其他囊肿类密度。结论术前CT诊断肝包虫囊肿胆瘘具有临床价值。
Objective To review the cases of hepatic hydatid cyst gallbladder fistula confirmed by surgery and pathology and to improve the understanding of hepatic hydatid cyst fistula. Methods A retrospective analysis was performed on CT cases of 22 cases of hepatic hydatid cyst fistula confirmed by surgery. Results Twenty - two cases of hepatic hydatid cyst with gallbladder fistula showed smaller cyst tension, irregular shape and obvious internal capsule rupture in 19 cases. See, respectively, as “Crescent sign” “cystic capsule sign” and “streamer-like shadow.” 2 cases did not see the internal capsule rupture, gallbladder see scattered irregular gas shadow. After a slight increase in the partial wall of the cyst, the cyst density was significantly higher than that of other cysts. Conclusion Preoperative CT diagnosis of hydatid cyst fistula has clinical value.
