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.

We described herein the first case of primary $Sj{\ddot{o}}gren^{\prime}s$ syndrome in Korea which presented with multiple cysts caused by only peribronchiolar lymphocytic infiltration, a rare pulmonary manifestation in $Sj{\ddot{o}}gren^{\prime}s$ syndrome, and was confirmed by surgical lung biopsy. A brief review of the literature has been included.

In 2019, the American College of Radiology announced Lung CT Screening Reporting & Data System (Lung-RADS) 1.1 to reduce lung cancer false positivity compared to that of Lung-RADS 1.0 for effective national lung cancer screening, and in December 2022, announced the new Lung-RADS 1.1, Lung-RADS^Ⓡ 2022 improvement. The Lung-RADS^Ⓡ 2022 measures the nodule size to the first decimal place compared to that of the Lung-RADS 1.0, to category 2 until the juxtapleural nodule size is < 10 mm, increases the size criterion of the ground glass nodule to 30 mm in category 2, and changes categories 4B and 4X to extremely suspicious. The category was divided according to the airway nodules location and shape or wall thickness of atypical pulmonary cysts. Herein, to help radiologists understand the Lung-RADS^Ⓡ 2022, this review will describe its advantages, disadvantages, and future improvements.

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.
