UNASSIGNED: The case is a newborn of 38weeks\' gestation who was followed by prenatal ultrasound control for suspected adenomatous cystic malformation type III in the left lung from week 22. She did not present complications during pregnancy. The study of Genetics and serological test were negative. She was born by urgent caesarean section due to breech presentation without requiring resuscitation, weighing 2.915 g. She was admitted to the Unit for study, remaining stable throughout her stay, with a normal physical examination. Atelectasis of the left upper lobe was appreciated by chest X-ray. Pulmonary ultrasound on the second day of life showed signs of consolidation in the left posterosuperior field with air bronchogram, without other alterations. In subsequent ultrasound controls, an interstitial infiltrate was observed in the left posterosuperior region, compatible with progressive aeration of the area, which was maintained until 1 month of life. The computed tomographic scan performed at 6months of age shows hyperlucency and increased volume in the left upper lobe with slight hypovascularization, accompanied by paramediastinal subsegmental atelectasis. There was a hypodense image at the hilar level. These findings were compatible with bronchial atresia, later confirmed by fiberoptic bronchoscopy. At 18months of age, surgical intervention was performed.
UNASSIGNED: We present the first case of bronchial atresia diagnosed by LUS, thus adding new images to the very scarce literature currently available.
■该病例为妊娠38周的新生儿,从第22周开始,对疑似左肺III型腺瘤囊性畸形进行产前超声检查。她在怀孕期间没有出现并发症。遗传学和血清学试验均为阴性。她出生时是由于臀位出现而紧急剖腹产,不需要复苏,体重2.915克。她被单位录取学习,在她逗留期间保持稳定,正常体检。胸部X线检查发现左上叶肺不张。生命第二天的肺部超声显示左后上野有巩固的迹象,并伴有空气支气管图。没有其他改动。在随后的超声控制中,在左后上区域观察到间质浸润,与该区域的渐进曝气相容,一直维持到生命的1个月。在6月龄时进行的计算机断层扫描显示左上叶的高透明度和体积增加,伴有轻微的血管形成。伴有副纵隔亚节段肺不张。在肺门水平有一个低密度图像。这些发现与支气管闭锁相符,后来经纤维支气管镜证实。在18个月大的时候,进行了手术干预。
■我们介绍了由LUS诊断的第一例支气管闭锁,从而为目前非常稀缺的文献添加新的图像。
