A 9-year-old, castrated male Malamute dog was presented with chronic cough. On thoracic computed tomography, non-tapered and dilated peripheral bronchi were detected. Bronchoarterial ratio was about 2.2. The dilated bronchi appeared as a cluster of grapes especially in left cranial, left caudal and right middle lung lobe. Based on the computed tomographic findings, the diagnosis was made as the saccular type of bronchiectasis.

PET/CT is taken 1 hour after $^{18}F$-FDG(F-18-fluoro-2-deoxy-D-glucose) injection. However, these would be often delayed for more than 2 or 3 hours due to equipment fault or unexpected situation. In the study, SUV(standardized uptake value) were measured from got image over time according to the parts of the body. As a result, there were great and small decrease in liver(middle of the right hepatic lobe), fat(Lt pelvis), lung (Rt upper lobe), aorta(ascending aorta level) of the body in delayed image, and ${\Delta}$SUVmax was increase of 37% in bone only(L5 vertebral body) of the body. ${\Delta}$SUVmax was increase of 37.6% in lesion, and the contrast degree was greater because of uptake increase in lesion and uptake decrease in the normal body.

Epithelioid hemangioendothelioma(EH) is a rare pulmonary vascular malignancy. Clinically, EH has been considered as an indolent, generally non-aggressive tumor. We report a case of EH which was confirmed by open lung biopsy. A 34-year-old woman was admitted for further evaluation of multiple small(less than 2cm in size) nodules, incidentally detected on screening chest radiograph. The chest CT showed multiple, relatively well-marginated, variable sized nodules at both whole lung. Transbronchial lung biopsy and transthoracic needle aspiration were nondiagnostic and open lung biopsy was performed from right middle lobe of lung. On light-microscopic examination, the nodules were composed of a poorly cellular hyaline core and a more cellular peripheral zone which extended into air space in a micropolypoid fashion and obliterated blood vessels. The tumor cells at the peripheral zone had intracytoplasmic vacuoles which suggested primitive, vascular differentiation. Immuno-histochemical study revealed the cellular area which gave positive reaction to factor VIII-related antigen. She received no specific therapy after open lung biopsy and chest X-ray films had showed no change for about two years.

Congenital cystic adenomatoid malformation of the lung is a rare pulmonary malformation, Although it is one of the most common congenital anomalies which cause acute respiratory distress in the newborn infants, characterized by marked proliferation of terminal respiratory structures. We have experienced an unusual case of congenital cystic adenomatoid malformation associated with pectus excavatum. The patient was 3-year-old female who suffered from cough and high fever for 20 days, and antibiotic therapy was given in other hospital before transfer to our hospital. The findings on chest X-ray, chest CT, aortogram, and selective bronchial arteriogram showed cystic lesions in the right upper and middle lobe accompanied but severe pectus excavatum. Right bilobectomy for pulmonary lesion and costosternal elevation for pectus excavatum was performed simultaneously with successful result. The postoperative course was uneventful and the patient was discharged on the twentieth postoperative day.

Background: Pulmonary thromboembolism(PTE) is a life threatening disease that needs early diagnosis. Spiral CT angiography depict thromboemboli in the central pulmonary vessels with greater than 90% sensitivity and specificity, which approaches the results of pulmonary angiography in the Prospective Investigation of Pulmonary Embolism Diagnosis(PIOPED) study. This study was performed to evaluate the findings and the diagnostic value(clinical utility) of the spiral CT angiography with 2D image(multiplanar reformation) and 3D images(Shaded surface display, Minimal intensity projection) in the pulmonary thromboembolism. Methods: We retrospectively analysed spiral CT angiography and pulmonary angiography, lung scan and clinical recordings of 20 patients who had PTE diagnosed by spiral CT angiography(n=19 cases) or pulmonary angiography(n=l case) from September 1997 to August 1998. Among 20 patients who had underwent spiral CT angiography, 14 patients could be performed lung perfusion scan at the same time. We analyzed the vascular and parenchymal change in spiral CT angiogram. Results: Anatomical distribution of PTE was as follows: 1) left lung(n= 103)

Kawasaki disease is an acute febrile vasculitis that occurs predominantly in young children under 5-years-old. The patients present generally with a high spiking fever that is unresponsive to antibiotics and lasts for more than five days at least. Prolonged fever has been shown to be a risk factor in the development of coronary artery disease. It seems to be certain that infectious agents are associated with the pathogenesis of Kawasaki disease. The differential diagnosis of Kawasaki disease must rule out infectious diseases including scarlet fever, toxic shock syndrome, measles, and so on. This is very important for adequate treatment and prevention of cardiac complications of Kawasaki disease. We experienced a 25-month-old boy who had high fever and pneumonic consolidation in the right middle and lower lobe of the lung that was considered as mycoplasma pneumonia on admission and developed coronary artery aneurysmal dilatation during treatment with roxythromycin.

Pulmonary pneumatoceles are air-filled thin-walled spaces within the lung and are rare in adult cases of pneumonia. We report the case of a 74-year-old male who was admitted with a cough and sputum production. He had been treated with oral dexamethasone since a brain tumorectomy 6 months prior. Contrast-enhanced computed tomography (CT) of the chest revealed a large pneumatocele in the right middle lobe and peripheral pneumonic consolidation. Bronchoalveolar lavage was performed; cultures identified extended-spectrum ${\beta}$-lactamase (ESBL) producing Proteus mirabilis. A 4-week course of intravenous ertapenem was administered, and the pneumatocele with pneumonia resolved on follow-up chest CT. To the best of our knowledge, this is the first reported case of pulmonary pneumatocele caused by ESBL-producing P. mirabilis associated with pneumonia.

Lymphocytic interstitial pneumonia (LIP) is a rare disorder characterized by a diffuse infiltration of the alveolar space, interstitium by lymphocytes, plasma cells, and reticuloendothelial cells. Although its etiology is unknown, LIP has been associated with autoimmune disorders and with viral infections. Because it's clinical and radiographic features are nonspecific, a confirmatory diagnosis is performed by open lung biopsy. A 59-year-old female presented dry cough, which had been present for 1 month. On initial findings of multifocal consolidation at the right middle lobe on both lower lobes in chest radiography, the first diagnosis of cryptogenic organizing pneumonia was suggested. On open lung biopsy, LIP was diagnosed. The patient had no autoimmune disease, viral infection or monoclonal gammopathy. After 3 months of corticosteroid treatment, the patient experienced improved symptoms, reduced abnormalities on chest radiography, and improved pulmonary function testing.

Background: The lung abscess predominantly occurs on a dependent region, because its major predisposing factor is aspiration. However, a lung abscess appeared on a nondependent region occasionally. Traditionally bronchoscopy has been performed in patients with lung abscess on a nondependent region for evaluating the endobronchial obstruction such as bronchogenic carcinoma. But the clinical characteristics and necessities of bronchoscopy in patients with lung abscess located at nondependent region have not been discussed previously. Thus, we investigated the underlying etiologies and the necessities of bronchoscpy in patients with lung abscess in a nondependent region. Method: Fifteen patients with cavitary lesion on a nondependent location have been studied retrospectively by reviewing their clinical records, chest PAs, computerized tomograms, and bronchoscopic findings. Results: 1) Most patients were older than 30 years except one, and their mean age was 51 years. The ratio of male to female was 6.5:1. 2) The underlying etiologies were bacterial infections in 13 cases, and tuberculous infection in two cases. However, bronchogenic carcinoma was not found as its etiology. 3) Among thirteen bacterial lung abcess, tweleve cases located at right middle lobe. 4) The findings of bronchoscopy were non-speicifc mucosal change in 8 cases and segmental obstructions in 2 cases. There were no malignant evidences in the finings of cytology and bronchscopic biopsy. 5) Among thirteen bacterial lung abcess, eleven patients showed good clinical reponse to antibiotic therapy. Conclusion: The necessity of early bronchoscopy may need to be re-evaluated in the lung abscess on a nondependent region, unless evidences of bronchial obstruction or bronchogenic carcinoma exist. The pulmonary tuberculosis shoud be regarded as the underlying etiology of the nondependent lung abscess.
