Pulmonary Sequestration: Ultrasonic Appearance

Pulmonary sequestration is a congenital anomaly in which aberrant, nonfunctioning lung tissue re-ceives its entire blood supply from the systemic circulation. Early diagnosis may be difficult be-cause the radiographic and clinical presentation may be mimicked by other lesions, such as cystic adenomatoid malformation, congenital bron-chogenic cyst, pleural effusion, congenital dia-phragmatic hernia, or large diaphragmatic even-tration. The following case is presented to describe and illustrate the sonographic appearance of pulmonary sequestration. To our knowledge, a case in which sonography provided the correct preoperative diagnosis has not been reported. CASE REPOR
