A 2-year-old, female Pomeranian dog was referred for dyspnea. Thoracic radiographs revealed left-sided mediastinal shift, increased soft tissue opacity in the caudal aspect of left thorax with loss of the left diaphragmatic silhouette, and dorsal elevation of mediastinal structures and heart from the sternum by lung tissue. The left main bronchus was visualized as an air-bronchogram and observed to abruptly discontinue at the level of the 10th rib. Thoracic computed tomography (CT) revealed absence of the left lung parenchyma and left pulmonary vessels with a rudimentary left main bronchus. The case was congenital pulmonary aplasia diagnosed via radiography and CT.

Congenital thoracic ectopic kidney is a very rare developmental disorder and the rarest type of ectopic kidney. This condition is usually asymptomatic and detected incidentally on routine chest radiography. Most cases of thoracic ectopic kidney develop in adulthood and during the neonatal period, and congenital thoracic ectopic kidney rarely develops in children. Most patients are asymptomatic, and the treatment depends on the diagnosis. Herein, we report a rare case of ectopic thoracic kidney associated with a diaphragmatic hernia in a 15-month-old male infant, who presented with periodic severe irritability. The thoracic ectopic kidney was detected as a mass in the right base of the chest on routine chest radiography.

Ninety-nine dogs diagnosed as tracheal collapse were reviewed for 2002-2003 year at Veterinary Medical Teaching Hospital, Seoul National University with clinical records and radiographs. Dogs were ranged in age from 1 to 15 years old (average 8.23 years old) and in weight from 1.2kg to 10.3kg (average 3.3kg). The population included 58 females (6 spayed) and 41 males (8 castrated). It is highly predominant in Yorkshire terrier (64, 64.6%) followed by Pomeranian (10, 10.1 %), Poodle and Chihuahua (8, 8.1%), Maltese (4, 4.0%), mixed breed (3, 3.0%), Cocker Spaniel and Pug (1, 1.0%). The incident rate of female dogs (59%) exhibited relatively higher than that of male dogs (41%). The most prevalent occurrence location was thoracic inlet (60%) of all and carina region (15%), intrathoracic trachea (14%) and cervical trachea (11 %) showed similar rate. Conclusively, tracheal collapse was observed in completely matured or old small breed dogs, largely Yorkshire terrier, on thoracic inlet primarily regardless of gender. These tendencies were apparently similar to previous reports.

This study was performed to compare the radiographic and echocardiographic features of cardiovascular changes between small and large dogs with heartworm diseases. Total of 49 dogs from two institutions were included in this study. The dogs were diagnosed with heartworm infestation and underwent thoracic and echocardiography. On thoracic radiographs, vertebral heart scale, reverse D shape, main pulmonary artery dilation, peripheral pulmonary artery dilation, and evidence of right heart failure were evaluated. On echocardiographs, visibility of worms, main pulmonary artery to aortic root (MPA/Ao) ratio, right to left ventricular basal diameter (RVD/LVD) ratio, and pulmonary hypertension were evaluated and analyzed between small and large dogs. The proportion of reverse D shape of the heart and accuracy for right ventricular hypertrophy in small dogs were lower than those of the large dogs. For echocardiographic parameter, the MPA/Ao and RVD/LVD ratio in the small dogs were significantly lower than those of the large dogs. As the results, thoracic radiography have a tendency to underestimate the severity of HWD in small dogs and should be used with echocardiography.

A 5-year-old castrated male domestic shorthair cat was referred for further investigation of pulmonary nodules incidentally detected on thoracic radiographs. Thoracic radiographs identified ill-defined soft tissue opacity nodules with small faint mineral opacity. Thoracic computed tomography (CT) revealed that bronchial dilation and bronchial wall thickening in bilateral cranial and accessory lung lobes. Round to ellipsoid mineralized concretions were found embedded in the intrabronchial soft tissue attenuation material. Based on radiography, CT, and cytology, the patient was tentatively diagnosed as having broncholithiasis with chronic bronchitis. This report described the CT diagnosis of broncholithiasis, which has been rarely reported in a cat.

Castleman disease is a relatively rare disease, characterized by well-circumscribed benign lymph-node hyperplasia. The disease may develop anywhere in the lymphatic system, but is most commonly reported as unicentric Castleman disease in the mediastinum along the tracheobronchial tree. It is usually asymptomatic and detected on plain chest radiography as an incidental finding. We report an incidentally detected case of Castleman disease in the paravertebral space that was preoperatively diagnosed as a neurogenic tumor and treated by complete surgical resection.

A 51-year-old woman visited our hospital with massive hemoptysis. She had suffered from recurrent hemoptysis for five years and had undergone bronchial artery embolization many times. The patient had a history of pulmonary tuberculosis and bronchiectasis. Chest radiography showed consolidation around the nodule in the lateral basal segment of the right lower lobe. We successfully performed a right lower lobectomy. The histological study of the resected specimen showed a vegetable foreign body and clumps of Actinomyces, indicating actinomycosis, which was suggested to be the cause of the hemoptysis. This was a very rare case of hemoptysis caused by a vegetable foreign body and actinomycosis.

A 36-year-old man visited Yeungnam University Hospital with a sudden onset of palpitation, headache, and was found to be hypertensive. Chest radiography showed a 6 cm sized mass lesion on the posterior mediastinum. A biochemical study showed elevated levels of catecholamines. An I-123 metaiodobenzylguanidine scan revealed a hot uptake lesion on the posterior mediastinum. The patient was prepared for surgery with ${\alpha}$ and ${\beta}$ blocking agents. Two months later, we removed the tumor successfully. A histological study proved that the resected tumor was mediastinal pheochromocytoma. Functional mediastinal pheochromocytomas are rare. Therefore, we reported the case with a literature review.

This study was carried out to improve service efficiency and to cope with a emergency situation in emergency radiography, through analysis of the radiographic distribution and literature cited about emergency care. Data collection of radiographic distribution was surveyed for 761 emergency outpatients who visit during JAN, 1994 at ER of the general hospital in Pusan city. The results is as follows: Emergency radiography rate of simple radiography was 61.1 %, special radiography 2.5 %, CT 12.6 %, and ultrasonography 6.7 %. In simple radiography rate, a high rate was distributed on male(63.6 %), thoracicsurgery part(90.0%), admission patient(74.9 %), and long stayed patient at ER. In special raiography rate, a high rate was observed in urologic part(28.6%), and in CT rate, observed neurosurgery part(49.2 %) and neurologic part(36.7%). Ultrasonography rate was high for female(8.8 %) and internal medicine part(15.9 %). There are distributed regional radiography rate in radiographic type that chest(55.3 %) is high in the simple radiography, urinary system(1.2%) in the special study, and brain(40.0 %) in the CT. Regional radiography rate according to diagnostic department also was showed highly for head(64.6%) in neurosurgery, chest(90.0%) in thoracic-surgery, abdomen(58.0%) in general-surgery, spine (40.0% ) in neuro-surgery, and pelvis(15.9%), upper extrimity(20.5%), and lower extrimity(31.8%) in orthopedic-surgery each. Mean radiographic case number per patient of simple radiography was sinificant on sex, age, transfer relation in both total and radiographic patients(p<0.05). Mean radiographic case number was highly distributed on male(2.2 case number) in sex, on thirties(2.7) in age, transfered patient(2.7) in patient type, and on neurosurgery(3.4) in diagnostic charged part. Total radiographic case number in regional part was highly distributed on chest(499 case number). Considering the above results, emergency radiographer should take care of the elder patient in emergency radiography and get hold of injury mechanism to decrease possible secondary injury during radiography. Because of high radiography rate of urinary system in special study, radiographer should know well about dealing with contrastmedia administration and related instrument. All radiographer who take charge emergency patient should cope with a emergency situation during radiography, Because head trauma patients is very important in patient care, especilly in CT at night, charged doctor should be always silted with CT room and monitoring-patient. Radiography was reqested by many diagnostic department in ER. Considering that rate of simple radiography is high, special room for emergency radiography should be established in ER area, and the radiographer of this room should be stationed radiologic technician who is career and can implement emergency patient care.

A 3-years-old female Pointer was evaluated for anorexia, dyspnea and exercise intolerance for 10 days. Auscultation revealed muffling of heart sound. There were leukocytosis, anemia, hypoalbuminaemia and hyperglobulinaemia on the blood profiles. Radiography showed severe pleural effusion. Thorax ultrasonographs described traped pleural effusion, pericardial effusion and collapsed right lung lobe(s). On CT images, thoracic neoplasia and lung torsion were ruled-out. Thoracocentesis with thoracoscopy and bacterial culture revealed pyothorax and pleuritis. The diagnosis of pyothorax in dogs and cats is based on clinical signs, radiography, thoracocentesis and cytology and culture of the exudate. In this case, various diagnostic medical imaging techniques (radiography, ultrasonography, CT and thoracoscopy) were used for diagnosis of pyothorax.
