肺隔离症是一种少见的肺组织发育异常的先天性疾病,作者报告1例用超声波检查得以诊断。患儿15个月,男性。胸部感染,X 线胸片示左肺基底部实变阴影,虽经抗生素适当治疗,残留的阴影数周后仍不消散。因怀疑局部胸腔积液而行超声检查,局部显示实质性肿块,并伴有囊性区。腹中线扫描发现,起自腹主动脉的一条异常血管,其一端延伸至胸部肿块,提示肺隔离症。之后,血管造影还证实静脉血经半奇静脉系统回流。外科切除证实为肺叶内型隔离症,病理检查证实肺组织发育异常并伴有多发的粘液囊肿,这点与超声所见的囊肿区相符。
Pulmonary sequestration is a rare congenital disease of lung tissue dysplasia, the authors report 1 case diagnosed by ultrasonography. Children 15 months, male. Chest infection, chest X-ray showed the base of the left lung consolidation shadow, although the appropriate treatment of antibiotics, the residual shadow still does not dissipate after a few weeks. Due to suspected local pleural effusion and ultrasound examination, the local showed substantial mass, and associated with cystic area. Abdominal line scan found that from the abdominal aorta an abnormal blood vessels, one end extends to the chest mass, suggesting that pulmonary sequestration. After that, angiography also confirmed venous blood through the azygos vein system reflux. Surgical resection was confirmed as pulmonary lobular sequestration, pathological examination confirmed lung dysplasia with multiple mucinous cysts, which is consistent with the cyst area seen by ultrasound.
