  • Lung homotransplantation was performed in 15 pairs of dog. Methotrexate and R.E.S. blocking were used to prolong the survival time. Details of handling the transplant, operative technique and management of the recipient were discussed and following results were obtained: 1]. 7 dogs out of 15 dogs of homotransplantation of lung were survived beyond 3 days. In the group of dogs treated with methotrexate, the average survival was 8.5 days, and in the group of dogs treated with R.E.S. blocking, the average survial was 9.7 days with longest survival of 17 days. 2]. The causes of immediate postoperative death in homotransplantation of dogs were lung edema and disruption of bronchial anastomosis. 3]. The main causes of death in successful homotransplantation dogs which were survived beyond 3 days were infection of lung parenchyma and bronchial necrosis rather than the occurence of graft rejection. 4]. Graft rejection was not revealed even after 7 days of operation in the group treated with methotrexate as well as in the group treated with R. E.S. blocking. This finding made it suggest that the R. E.S. blocking may be effective to control the rejection reaction. 5]. Even though the pulmonary function of transplanted lung was revealed the evidence of severe impairment immediate after operation by bronchospirometry, it was increased gradually and 10 days after operation the minute ventilation and oxygen uptake were decreased 8%, 13% respectively less than pre-operative one.

  • Lung hernia is defined as a protrusion of lung parenchyma beyond the confines of the musculoskeletal thorax. To date, less than 300 cases have been reported in the literature. The patients were 37 & 57-year-old men who had traumatic rib fractures in the past, whose chief complaint was a painless soft bulging mass increased in size during expiration or coughing and diminished during inspiration or quiet breathing. The primary repair was performed without any p stoperative recurrance. We report two cases of acquired herniation of lung first time in Korea with a brief review of literature.

  • A 16-year-old female Bengal tiger (Panthera tigris tigris) infected with Paragonimus kellicotti was described. Noticeable clinical symptom was not observed before death. At autopsy, numerous cysts were found on the pleural surface of the lung. The cysts were spherical, approximately 1.0 cm in diameter, bulge the pleura, and dark red-brown in color. Such cysts were also found in the deeper lung parenchyma, and usually contained adult flukes in pairs. Histopathologically, the cyst was lined with stratified squamous epithelium which arose from metaplasia of bronchial epithelium. Partial hyperplasia and necrotic foci accompanied with inflammatory cells were often observed in the squamous epithelium. The outer part of the cyst was consisted of fibrous connective tissue in which leukocytes were infiltrated. Catarrhal pneumonia was manifested in the adjacent lung tissues.

  • 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.

  • Pulmonary arteriovenous fistula is a rare congenital vascular malformation in the lung, resulting from erroneous capillary development, with incomplete formation or disintegration of the vascular septa that would normally divide the primitive connection between the venous and arterial plexus. The pathogenesis of its symptom is that unoxygenated and desaturated arterial blood enter into the pulmonary venous system directly. Recently we have experienced a case of multiple pulmonary arteriovenous fistula in a 15 year old male patient, who presented the symptom of cyanosis and dyspnea on exertion. The operation revealed well circumscribed and multilobulated aneurysmal lesion in left lower lobe with its subpleural and posterolateral basal location, and another aneurysmal lesion in inferior lingular segment of left lung. There was no abnormal connection between the fistula and systemic circulation. The left lower lobectomy was performed along with local extirpation of the inferior lingular segment of left lung. Both lesions showed angiomatous dilatation of the various sized vessels embedded in the parenchyma microscopically. Postoperative clinical course disclosed much improvement in symptoms and in the value of blood gas analysis. The patient was discharged without any complication.

  • An 11-year-old, intact male Shih Tzu presented with obesity, thin hair coat, and abdominal distention. The patient had previously received corticosteroid therapy for dermatitis. Thoracic radiographs showed incidental findings of a generally diffuse bronchointerstitial pattern and markedly radiolucent pleural lines between the middle and caudal lung lobes, but clinical signs related to the thoracic radiographic findings were absent. Echogenicity of the hepatic parenchyma was increased and bilateral adrenal glands were not enlarged on ultrasonography. On computed tomography, the central regions of the lung lobes showed ground-glass attenuation, the peripheral regions of the lung lobes were relatively hypoattenuated compared with the central regions, and hyperattenuated nodules were distributed throughout the pulmonary parenchyma. Iatrogenic hyperadrenocorticism and secondary pulmonary mineralization was diagnosed on the basis of diagnostic imaging and adrenocorticotropic hormone stimulation test.

  • Background: Lung abscess is necrosis of the pulmonary parenchyma caused by microbial infection. At present, clinical outcomes after treatment are good. However, the pulmonary parenchymal changes on the chest computed tomography (CT) after treatment are not well known. We studied the changes of pulmonary parenchyma on plane chest radiography and chest CT in patients with lung abscess following the administration of antibiotics. Methods: We retrospectively reviewed 39 patients who had lung abscess with or without combined pneumonia from January 2006 to July 2010. We studied the therapeutic response in plane chest radiography of them at 1, 2, or more than 3 months following treatment. If any chest CT of them during the study period, we reviewed. Results: Mean age of the patients was about $61.3{\pm}11.2$. Mean duration of antibiotics administration was about $36.7{\pm}26.8$ days. After 3 months of following plane chest radiography, 10 patients (36%) showed without residual sequelae among 28 patients. Findings from other patients showed decrease in densities (11 patients, 39%), fibrostreaky sequelae (4 patients, 14%) and bullae (3 patients, 10%). After more than 2 months, chest CT was checked only in 7 patients. Among the 7 patients, 4 patients showed no residual lesion, 3 patients showed decreased densities on plane chest radiography. Chest CT revealed fibrostreaky densities in 2 patients, ground glass opacities in 3 patients, bullous formation in 1 patient, and cystic bronchiectasis in 1 patient. Conclusion: After more than 2 months following treatment for lung abscess even though there were no lesions on plane chest radiography, chest CT showed fibrostreaky or ground glass opacity.

  • Primary hemangiopericytomas of the lung are uncommon sarcomas that arise from pericytes that surround the basement membrane of capillaries and small venules within the lung parenchyma. The presenting symptoms and signs depend on the location of the tumor and radiologic features are not diagnostic. The behavior of pulmonary hemangiopericytomas is difficult to predict and all tumors should be considered potentially malignant. Wide surgical excision remains the mainstay of treatment. We report a case of primary hemangiopericytoma of the lung with a brief review of literature.

  • Non-infectious granulomatous lung disease represents a diverse group of disorders characterized by pulmonary opacities associated with granulomatous inflammation, a relatively nonspecific finding commonly encountered by pathologists. Some lesions may present a diagnostic challenge because of nonspecific imaging features; however, recognition of the various imaging manifestations of these disorders in conjunction with patients' clinical history, such as age, symptom onset and duration, immune status, and presence of asthma or cutaneous lesions, is imperative for narrowing the differential diagnosis and determining appropriate management of this rare group of disorders. In this pictorial review, we describe the pathologic findings of various non-infectious granulomatous lung diseases as well as the radiologic features and high-resolution computed tomography imaging features.

  • A 42-year-old man was diagnosed with cancer of the right lower lung lobe with a posteparterial type of tracheal bronchus, in which the posterior segmental bronchus of the right upper lobe arose from the distal bronchus intermedius. A mass involved the distal bronchus intermedius, requiring a right lower bilobectomy with an additional posterior segmental resection of the right upper lung lobe. Thus, we performed a right lower bilobectomy and sleeve anastomosis of the posterior segmental bronchus of the right upper lobe to the proximal bronchus intermedius, sparing the pulmonary parenchyma of the same lobe.
