Intralobar pulmonary sequestration is rare congenital lung disease, in which systemic artery supplies a congenitally cystic portion of the lung. Patient was 19 years old male whose complaints were fever, chest pain and sputum. Chest film showed a round homogenous density and air-fluid level at the left lower lung field and on bronchogram, contrast materials did not enter the abscess pocket. By operation multiple lung abscess pockets at the lower lobe were noted. An aberrant artery, measuring 0.4cm. in diameter and 2 cm. in length, arised from the aorta just above the diaphragm and entered the pusterior basal segment of left lower lobe. After division of the artery, left lower lobectomy was done ana postoperative hospital course was uneventful. Pathologic findings were multiple lung cysts which were not connected to the left lower lobe bronchi and an aberrant artery which showed elastic lamillation and mild sclerotic change.

Congenital cystic adenomatoid malformation[CCAM of the lung is extremely rare. We have experienced an unusual case of congenital cystic adenomatoid malformation. The patient was 20-year-old male and had chest pain for 10 days. On simple chest x-ray and Thoracic CT scan, there was a large cystic mass surrounded with multiloculated round cysts with air fluid level on the right lower lobe of a lung. Right lower lobectomy was performed and the pathologic result was congenital cystic adenomatoid malformation.

쇼그렌 증후군은 림프구 침윤과 관련된 만성적인 염증성 자가면역 질환으로 아직 정확한 병태생리학적 기전은 밝혀지지 않았다. 45세 여자 환자가 내원 2년 전 전신 쇠약 및 피로감으로 입원하여 혈청 검사에서 anti-Ro/La antibody 양성, 흉부 단순방사선 및 컴퓨터 촬영에서 양 폐야의 다낭성 병변이 관찰되어 비디오 흉강경을 이용한 폐 생검 시행 결과 세기관지 주위에 림프구 침윤 및 다양한 크기의 폐낭종들이 관찰되어 쇼그렌 증후군의 폐 침범 의심하에 추가 검사 시행하려 하였으나 추적 관찰 되지 않았다. 2년 후 폐렴으로 입원하였으며, 다시 시행한 흉부 컴퓨터 단층촬영에서 다발성 낭성 변화는 큰 차이를 보이지 않았다. 쇼그렌 증후군의 폐 침범은 다양한 형태로 나타나는데, 단순히 세기관지 주위에 림프구 침윤에 의한 다낭성 폐 질환에 대한 보고는 극히 드물다. 따라서 본 저자들은 일차성 쇼그렌 증후군 환자에서 비디오 흉강경을 이용한 폐 생검으로 진단된 세기관지 주위에 림프구 침윤을 동반한 다낭성 폐 질환 1예를 경험하였기에 보고하는 바이다.

미국방사선의학회는 효과적인 국가 폐암 검진 시행을 위해 2019년도에 Lung CT Screening Reporting & Data System (이하 Lung-RADS) 1.0보다 폐암의 위양성을 줄이기 위해 개편된 Lung-RADS 1.1을 발표하였고, 2022년 12월에 새로운 Lung-RADS 1.1 개선안 Lung-RADS^Ⓡ 2022를 발표하였다. Lung-RADS^Ⓡ 2022은 Lung-RADS 1.0과 비교했을 때 결절의 크기는 소수점 첫째 자리까지 측정하고, 늑막근처 결절의 크기가 10 mm 미만인 경우까지 범주 2로 하며, 범주 2에서 간유리 결절의 크기 기준을 30 mm로 높이고, 범주 4B와 4X는 매우 의심으로 변경하며, 기도 결절의 위치와 비정형 폐 낭종의 형태와 벽 두께에 따라 범위를 나누었다. 이에 영상의학과 의사들의 개선된 Lung-RADS^Ⓡ 2022에 대한 이해를 돕고자, 이 종설에서는 Lung-RADS^Ⓡ 2022의 장점, 단점, 그리고 향후 개선점에 대해서 기술하고자 한다.

A 47-years-old woman presented with a 2-month history of a dry mouth and dry cough. The patient had been taking medication for Sj$\ddot{o}$gren's syndrome for approximately 7 years. The chest radiography showed multiple cystic lesions and a hazy density in both lower lung fields. The HRCT showed a diffuse ground glass like appearance and multiple variable sized cystic lesions in both lung fields. After medication, the symptoms were aggravated. Bronchoscopy was preformed with a transbronchial lung biopsy. The biopsies showed an infiltration of lymphocytes, neutrophils, monocytes and histiocytes through the interstitial space of the alveola and a widening of the alveolar septa. However, the histological findings of the cysts were not obtained. Sj$\ddot{o}$gren's syndrome is a slowly progressive inflammatory autoimmune disease, which is characterized by lymphocyte mediated destruction of the exocrine glands, with pulmonary involvement in approximately 19-65%, High-resolution CT is a sensitive technique for assessing the pulmonary involvement in patients with Sj$\ddot{o}$gren's syndrome. Although a lung biopsy is not always necessary for establishing a diagnosis of an interstitial lung disease in Sj$\ddot{o}$gren's syndrome. A lung biopsy may reveal a wide spectrum of changes ranging from a mild inflammatory response to end stage fibrosis with honeycombing. Because of the predominantly peribronchiolar inflammatory infiltration and inspissated secretions the cysts were suspected to have been formed by the ball-valve phenomen. However, no definite evidence was obtained.

The congenital cystic adenomatoid malformation of the lung consists of an enlarged, meaty, multicystic lobe with smooth-walled cysts of varying sizes, which can communicate with major bronchi through malformed air passages that usually lacks cartilage. This abnormality is usually symptomatic in infancy with signs of respiratory distress such as tachypnea, substernal retraction and cyanosis. Prompt surgical resection is choice of treatment in life-threatening respiratory distress patients. We recently experienced a case of congenital cystic adenomatoid malformation of the lung in a patient with situs inversus totalis. The patient was 40 days old female who showed severe respiratory difficulty. Emergency left middle lobectomy was undergone successfully. Her postoperative course was uneventful. She was discharged from hospital on the postoperative eighth day in good condition.

The congenital cystic adenomatoid malformation [C.C.A.M.] of the lung is a rare lesion consisted of multiple cysts in the pulmonary parenchyma lined cuboidal or columnar epithelium. The C.C.A.M. presents clinically in three ways:[1] stillborn or perinatal death, [2] progressive respiratory distress in the newborn, and [3] acute and chronic pulmonary nfections in the older infant and child. We recently experienced two cases of C.C.A.M. of the lung, and have good surgical results. The first case was 29 days old male and the second case was 16 month old female who have been suffered from severe respiratory difficulty and pulmonary infection repeatedly each other. The lobectomies were performed, and the postoperative course was uneventful.

The bronchogenic cysts result from an abnormal budding or branching of the tracheo-bronchial tree from the primitive foregut. Bronchogenic cysts may be pulmonary or mediastinal. The most common location for a mediastinal bronchogenic cyst is in relation to the carina. They are usually solitary. They usually are thin walled and contain fluid that is most often clear. The cyst is lined by ciliated columnar epithelium. The bronchogenic cyst i~ usually asymptomatic. They can cause pressure symptoms. When they become infected, symptoms do occur. We report 3 cases of bronchogenic cysts experienced at the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital. Case I, a man of 20 year-old, had a cyst at the site between aortic arch and left pulmonary artery. He complained cough and dyspnea. The cyst wasn`t communicated with tracheobronchial tree. Case II was 55-year-old male who had had hemoptysis. A huge cyst was located within the lower lobe of left lung and removed by pulmonary lobectomy. There were not any symptoms in Case III that was 6-year old girl. That cyst was located just next to the right main bronchus.

Pulmonary paragonimiasis is a relatively rare cause of lung disease revealing a wide variety of radiologic findings, such as air-space consolidation, nodules, and cysts. We describe here a case of pulmonary paragonimiasis in a 27-year-old woman who presented with a 2-month history of cough and sputum. Based on chest computed tomography (CT) scans and fluorodeoxyglucose positron emission tomography (FDG-PET) findings, the patient was suspected to have a metastatic lung tumor. However, she was diagnosed as having Paragonimus westermani infection by an immunoserological examination using ELISA. Follow-up chest X-ray and CT scans after chemotherapy with praziquantel showed an obvious improvement. There have been several reported cases of pulmonary paragonimiasis mimicking lung tumors on FDG-PET. However, all of them were suspected as primary lung tumors. To our knowledge, this patient represents the first case of paragonimiasis mimicking metastatic lung disease on FDG-PET CT imaging.

A 2-year-old female donkey (Equus asinus) was euthanized in the Pathology Department of Firat University, Elazig, Turkey. Necropsy disclosed the presence of 7 hydatid cysts distributed throughout the lung parenchyma. One of those cysts represented the parasite material of the present study and was molecularly identified through sequencing of a fragment of cytochrome c oxidase subunit 1 (CO1) and nicotinamide adenine dinucleotide dehydrogenase subunit 1 (NADH1) gene, as Echinococcus equinus. The generated CO1 sequence supports the presence of the dominant haplotype as has been described in Europe and Africa. The NADH1 sequence was found similar to sequences reported in equids in Egypt and the United Kingdom. The molecular identification of E. equinus in a donkey is being reported for the first time in Turkey.
