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.

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.

일측성 폐동맥 형성부전증은 매우 드문 선천성 기형으로서 대부분 팔로사징, 심실중격결손등과 같은 선천성 심기형을 동반하며 선천성 심기형이 동반되지 않은 고립성 편측 폐동맥 형성부전증은 극히 드물다. 이러한 환자들의 경우 성인이 될때까지 무증상으로 지내는 경우가 많으며 흉부 방사선 검사상 병변측 폐의 폐음영은 과투과되어 나타나며 흉곽은 작아진 소견으로부터 고립성 편측 폐동맥 형성부전증을 의심하게 된다. 저자들은 경미한 운동시 호흡곤란을 증상으로 내원한 50세 여환에서 흉부 전산화 단층촬영 및 환기-관류 스캔과 심초음파검사를 시행하고, 삼차원 재구성 전산화 심혈관 단층촬영을 이용하여 고립성 우측 폐동맥 형성부전증을 진단하고 치료한 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

독립적으로 발생하는 일측 폐동맥의 선천성 형성부전증은 매우 드문 기형이며 대부분 활로씨 4징과 같은 심장기형과 동반하여 발생한다. 동반된 선천성 심기형이라 폐감염이 없는 경우 대부분의 환자에서 증상이 없기 때문에 일차적 인 진단은 흉부방사선 촬영상에서 특징적인 양상을 보이는 것으로써 이루어진다 흉부 단순 촬영상 심장과 종격동이 병변측으로 전위되고, 병변측 폐동맥 음영이 보이지 않으며 흉곽의 크기가 정상측에 비하여 작고 횡격막이 거상된 양상을 보인다. 최근 저자들은 다량의 객혈을 주소로 내원한 48세 남자환자에서 우측폐동맥 형성부전증을 폐관류 스캔과 전산화 감골처리 폐동맥 조영술로 진단하고 우중·하엽절제술을 통하여 치료하였기에 문헌고찰과 함께 보고하는 바이다.

편측에 발생하는 폐동맥 형성부전증은 드문 선천성 기형으로 일반적으로 활로씨 4징과 같은 선천성 심혈관계 질환과 흔히 동반된다. 독립적으로 발생하는 폐동맥 형성부전증은 매우 드문 질환이고, 증상이 없는 경우가 많다. 이 질환은 흉부방사선촬영에서 우연히 의심되는 경우가 많으며 동반된 증상은 객혈, 피가 묻어 나오는 객담, 재발하는 폐감염, 운동 시 호흡곤란 등이다. 최근 저자들은 소량의 객혈과 지속적으로 피가 묻어 나오는 객담을 주소로 내원한 27세 남자 환자를 치험하였다. 저자들은 우측 폐전적출로 환자를 효과적으로 치료하였기에 관련된 문헌과 함께 보고하는 바이다.

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.

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.
