目的提高对脾肾包虫囊肿及其破裂感染影像学表现的认识。方法报告6例经手术病理证实的肾脾包虫囊肿的超声与CT所见,并分析本病的破裂感染及鉴别诊断。结果单纯型包虫囊肿2例,超声显示为边缘清晰的囊性无回声区。CT呈水样均匀低密度囊性肿物,边缘光整。多子囊型4例,声像图母囊内见子囊形成的小无回声区,呈“囊中囊”征象。CT显示为母囊内多个更低密度的子囊。多子囊型中破裂感染1例,其内外囊分离,内囊膜塌陷,伴内外囊壁不规则钙化。结论B超与CT对肾脾包虫囊肿的诊断、分型及有无破裂感染的诊断颇为准确。
Objective To improve the understanding of the imaging manifestations of splenic renal hydatid cyst and its rupture infection. Methods Six cases of renal cystic echinococcosis confirmed by surgery and pathology were reported by ultrasound and CT, and the diagnosis of the disease was analyzed with differential diagnosis. Results Simple hydatid cyst in 2 cases, ultrasound showed a clear cystic anechoic area. CT showed a uniform low-density cysts of water samples, edge finishing. 4 cases of multiple ascapsular type, the sonographic capsule within the sonography of the sonogram to form a small echo-free area, was “bladder sac” signs. CT showed multiple lower density ascus within the parent capsule. One case of multiple ascapsular rupture infection, the separation of the internal and external capsule, the collapse of the inner capsule, with irregular calcification of the outer wall. Conclusion B-ultrasound and CT diagnosis of renal cystic echinococcosis, typing and whether the diagnosis of rupture infection is quite accurate.
