  • Objective: To describe the anatomic locations and imaging features of posterior lung herniation in unilateral pulmonary agenesis and aplasia, focusing on radiograph-CT/MRI correlation. Materials and Methods: A total of 10 patients (seven with pulmonary agenesis and three with pulmonary aplasia, male: female = 1:9, mean age 7.3 years, age range from 1 month to 20 years) were included. Chest radiographs (n = 9), CT (n = 9), and MRI (n = 1) were reviewed to assess the type of lung underdevelopment, presence of anterior and posterior lung herniation, bronchus origin, supplying artery, and draining vein of the herniated lung. Results: Pulmonary agenesis/aplasia more commonly affected the left lung (n = 7) than the right lung (n = 3). Anterior lung herniation was observed in nine of the 10 patients. Posterior lung herniation was observed in seven patients with left pulmonary agenesis/aplasia. Two patients showed posterior lung herniation crossing the midline but not beyond the aorta, and five patients showed the posteriorly herniated right lower lobe crossing the midline to extend into the left hemithorax farther beyond the descending thoracic aorta through the space between the esophagus and the aorta. This anatomical configuration resulted in a characteristic radiographic finding of a radiolucent area with a convex lateral border and a vertical medial border in the left lower lung zone, revealing a tongue-like projection on CT and MRI. Conclusion: Posterior lung herniation occurs in unilateral left lung agenesis/aplasia. Approximately 70% of the cases of posterior lung herniation reveal a unique radiolucent tongue-like projection in the left lower lung zone on imaging studies, which is caused by the extension of the posteriorly herniated right lung farther beyond the descending aorta.

  • A 12-month-old boy was diagnosed with agenesis of the right lung. Mediastinal deviation progressed to the diseased side as the patient matured; therefore, tracheal distortion developed. As a result, tracheal compression developed between the vertebral body and aorta. The patient was repeatedly admitted to the hospital because of recurrent pulmonary infection and combined severe respiratory distress. Diaphragm translocation was performed to treat the patient. The postoperative course was favorable, and computed tomography scan findings and symptoms had improved at 1 year after surgery.

  • A unilateral pulmonary artery agenesis, which develops occasionally as one of the associated anomalies in congenital cardiovascular defect like as tetralogy of Fallot, is very rare anomaly as an isolated congenital defect. The diagnostic approach for the pulmonary artery agenesis is first suggested by the unique appearance of the involved lung on a routinely checked chest roentgenogram, because most patients are asymptomatic unless pulmonary infection had been superimposed. We have recently experienced a case of left pulmonary artery agenesis, which was diagnosed by perfusion scan, digital subtraction angiogram and then treated by left pneumonectomy in a 9 year-old boy, and presented hereby with the review of relevant literature.

  • Agenesis of the hemidiaphragm is unusual congenital anomaly associated with a high mortality. A case of congenital agenesis of left diaphragm was experienced in 22-day old male patient who was dyspneic and cyanotic on admission. Emergency exploration through the left eight interspace thoracotomy showed complete agenesis of the left diaphragm. The stomach and transverse colon covered with peritoneal sac was partially herniated into left hemithorax. The left lung was slightly hypoplastic. This neonate had no intestinal malrotation. The defect was reconstructed using Dacron graft. Dacron patch was sutured with interrupted Ethibond to chest wall anteriorly, esophagus aorta and costomediastinal sinus medially, and the tenth rib posterolaterally. Postoperatively, Extubation was performed at 1st day, but some respiratory difficulty was noted. Severe dyspnea was occurred at postoperative 11th day and so reintubation was done. Intermittently ventilatory support and intravenous alimentation were continued for 9 days after that. Thereafter he had no respiratory problems at discharge.

  • 폐 형성 저하증은 폐 무발생의 한 분류이다. 폐 무발생은 대부분 출생시 진단되는 매우 드문 질환으로, 심혈관계 기형과 같은 다른 기형이 흔히 동반된다. 소아기에 사망할 수도 있지만, 정상적인 성장을 하는 경우도 있다. 저자들은 수술 전 흉부 전산화 단층촬영에서 종격동의 심한 우측 편위와 우측 폐 실질의 허탈이 관찰되었던 폐 형성 저하증이 있는 젊은 여자에서 우측 측방 개흉술을 통한 승모판막 성형술을 시행하였다.

  • Developmental pulmonary abnormalities are known as rare condition. diagnosis was made at autopsy in the early cases reported, however, as diagnostic aids such as X-ray, bronchography, bronchoscopy and exploratory thoracotomy have come into use, the condition is being discovered more often recently in living persons, and it appears to occur with sufficient frequency to merit consideration in the differential diagnosis of certain chest conditions. According to Schneider and Boyden there are three main types of this abnormality: [1] Agenesis, in which there is complete absence of one or both lungs; there is no trace of bronchial or vascular supply or of parenchymal tissue. [2] Aplasia, in which there is suppression of all but a rudimentary bronchus which ends in a blind pouch; there are no vessels or parenchyma. [3] Hypoplasia, in which the bronchus is fully formed but is reduced in size and ends in a _ flesh structure which usually lies within the mediastinum. Rudimentary pulmonary parenchyma may be present around the bronchial stump and often is the site of cystic malformation. We experienced one case of hypoplastic lung with cystic malformation which was originated from a small aberrant rudimentary bronchus, and the rudimentary bronchus was branched from the right side of tracheal end. The diagnosis was finally confirmed by the histopathological finding. Now, we report this case with a brief review of literatures.

  • Fourteen cases of funnel deformity, 11 were male and the others female, treated over a eleven-year period, are presented. The overall results with the methods described by the authors, Wada, Shannon, Adkins and Ravitch appear to be excellent. The symmetric depression was more common In children under the age of 12 years and asymmetric one Increased after the age of 12. Six cases of abnormal cardiac auscultatory findings revealed no consistent hemodynamic abnormalities. An 21-year-old female was associated with left lung agenesis and dextroversion of the heart, and a 6-year-old boy with congenital bronchogenic cyst who underwent right upper lobectomy. EKG changes associated with the anomaly were observed in all. Pulmonary function test showed the range from normal to moderate restriction which did not Improve in only one patient after operation, but the patient did not complain any restriction In activity. Some transient complications were developed which resulted in improvement.

  • Four patients with funnel chest deformity corrected in the Department of Thoracic Surgery, Seoul National University Hospital are presented. The first case was a 21-year old female with cyanosis, clubbed fingers and systolic murmur on the left infrascapular region on physical examination associated with agenesis of the right lung. The deformity was of asymmetrical funnel chest, in which the left hemithorax was more sunken. She was corrected by the method of Funnel Costoplasty of Wada. The second case was a three years old boy whose anterior chest wall was symmetrically deformed, and he was corrected by the method of Ravitch using Adkins strut under the sternum. The third was a 22-year old man with symmetrical deformity, and was corrected by the method described by Shannon in 1973. The last patient was a 22-year old man and he had dyspnea on exertion, palpitation and apical systolic murmur with symmetrical funnel chest deformity. He was also corrected by Ravitch operation, All of them has excellent result.

  • 저자들은 간헐적인 혈담을 주소로 내원한 젊은 남자 환자에서 폐동맥 고혈압을 동반하지 않은 선천성 편측 폐동맥 형성부전증을 진단하여 보고하는 바이다. 선천성 편측폐동맥 형성부전증은 심혈관계 기형 없이 단독으로 일어나는 경우 대부분의 환자에서 경과 관찰 중 특이한 증상 없이 잘 지내지만, 일부 환자에서는 대량 객혈, 심각한 폐동맥 고혈압과 심부전증이 발생하기도 한다. 따라서 조기진단과 주의 깊은 경과 관찰이 중요하다. 폐동맥 고혈압을 가지고 있는 환자에서는 치료 결정에 있어 심도자 검사 및 폐혈관 쐐기조영술을 시행하여 수술적 치료 또는 폐동맥 고혈압에 대한 약물 치료가 고려되어야 한다.
