pneumonia outbreak caused by a novel betacoronavirus, the 2019 novel coronavirus (2019-nCoV), began in Wuhan, China. We report the epidemiological and clinical features of the first patient with 2019-nCoV pneumonia imported into Korea from Wuhan. This report suggests that in the early phase of 2019-nCoV pneumonia, chest radiography would miss patients with pneumonia and highlights taking travel history is of paramount importance for early detection and isolation of 2019-nCoV cases.]]>

We report two cases of parenchymal air-fluid level in emphysematous lungs. Plain chest radiograph showedpneumonic consolidation with an air-fluid level. HRCT in the supine position showed intrapulmonary fluidcollection with an air-fluid level, which moved to the dependent portion when the patient was in the proneposition. When pneumonia developed in severe emphysematous lungs, a movable parenchymal air-fluid level can bevisualized, though the presence of this on plain chest radiographs cannot be interpretated as hydropneumothorax.

PURPOSE: To compare chest radiographic findings of pulmonary tuberculosis in non-AIDS immunocom- promised adult patients with those in immunocompetent patients. MATERIAL AND METHOD: Eighty six patients who had pulmonary tuberculosis were included in the study. Of these, 41 were non-AIDS immunocompromised adult patients and 45 were immunocompetent adult patients. Chest radiographs obtained from 86 patients were retrospectively evaluated with regard to the followings ;the anatomic distribution and extent of tuberculous lesions, typical or atypical patterns of radiographic findings. We then compared the results in non-AIDS immunocompromised adult patients with those in immunocompetent adult patients. RESULTS: The characteristic manifestation of pulmonary tuberculosis was a tendency of pulmonary lesions to localize in the apico-posterior segments of the upper lobe and the superior segment of the lower lobe in both groups but more wide distribution such as the anterior segment and the lingular segment of the upper lobe and the basal segments of the lower lobe was frequently identified in non-AIDS immunocompromised adult patients, and also bilateral, multisegmental and multilobular extents were common findings. in immunocompetent adult patients, more common findings were in local exudative and productive lesions and several cavities in preferential sites. Atypical plain radiographic findings were more common in non-AIDS immunocompromised adult patients, and which were multiple cavitary lesions, wide extent of bronchogenic spread and tuberculous pneumonia, and .miliary disseminations and mass like lesions. CONCLUSIONS: Pulmonary tuberculosis in non-AIDS immunocompromised adult patients is characterized by frequent bilateral distribution, wide pulmonary extent, and atypical radiographic findings.

Varicella is a contagious infection in childhood disease typically affecting children aged 2-8 years and usually follows benign outcome. In the adult, clinical presentation is more severe and more commonly associated with complications. Varicella pneumonia, although rare, is a potentially life-threatening complication that should be suspected in any adult with varicella and respiratory symptoms. We report a case of varicella pneumonia in immunocompetent patient. The characteristic radiographic findings consisted of diffuse scattered coarse nodular infiltrations, less than 1cm sized, with ground glass opacity and consolidation in both lung fields. The patients was started on intravenous acyclovir. The chest radiograph performed 2 weeks later showed complete resolution of the pulmonary lesions.

1. A study on chest radiographic findings of 54 cases with pneumonia like symptoms was performed. Of 54 cases,8 cases were confirmed to be leptospirosis and 7 cases were leptospirosis combined with Korean hemorrhagic fever.2. Of 8 cases of leptospirosis, 4 cases showed abnormal chest radiographic findings: acinar nodular type 2,massive cofluent consolidation type 2. Of 7 cases of leptospirosis combined with Korean hemorrhagic fever: acinarnodular type 3, massive confluent consolidation type1, and increased interstitial markings type 1 respectively. 3.It was considered to be difficult to diagnose the leptospirosis on chest radiographic findings alone, especiallythe case combined with Korean hemorrhagic fever.

PURPOSE: To assess the incidence of aspiration pneumonia in infants with cleft palate and to compare the incidence between complete and incomplete types of cleft palate. MATERIALS AND METHODS: A review of medical records revealed 100 infants who had undergone initial surgery to repair cleft palate in our hospital during a recent three-year period. Aspiration pneumonia was defined as the coexistence of pneumonia at chest radiography with a history of frequent choking during feeding. The anatomic distribution of aspiration pneumonia was analyzed, and the incidences of aspiration pneumonia in infants with complete and incomplete cleft palate were compared. RESULTS: Among 100 children, aspiration pneumonia was found in 35 (35%). Those with complete and incomplete cleft palate showed similar incidences of the condition (27 of 70 [39%] vs 8 of 30 [27%], p=0.36). Pneumonia was most commonly seen in the left lower lobe (11 of 35), followed by the right upper and lower lobes. CONCLUSION: Aspiration pneumonia is frequently associated with infants with cleft palate. There is no statistical difference in the incidence of aspiration pneumonia between the complete and the incomplete cleft palate group.

PURPOSE: The aim of this study was to evaluate whether or not the early use of steroid is useful for treating Mycoplasma pneumoniae pneumonia. METHODS: A prospective study was conducted on 85 patients with M. pneumoniae pneumonia admitted to Gwangju Christian Hospital between September 2015 and April 2016. A total of 85 patients were enrolled. Of these, 33 were treated with steroids (methyl-prednisolone 1 mg/kg/day), while 52 were not; both were treated with macrolides. The overall duration of fever was compared between the 2 groups and findings on chest radiographs were evaluated for their deterioration. RESULTS: The duration of fever after admission (1.36±0.92 days vs. 2.17±1.30 days, P=0.003) and the overall duration of fever (4.42±2.13 days vs. 6.07±2.59 days, P=0.003) were significantly lower in the steroid group. The duration of fever before admission was not different between the steroid and macrolide groups (3.06±1.74 days vs. 3.90±2.21 days, P=0.068). On chest radiographs taken 3 days later, 1 of 33 patients in the steroid group and 5 of 50 patients in the macrolide group worsened, although there was no statistically significant difference between the 2 groups (P=0.395). There was no significant difference in the duration of hospitalization between the 2 groups (6.72±1.54 days vs. 6.92±1.87 days, P=0.618). CONCLUSION: Early administration of steroids on patients with M. pneumoniae pneumonia reduced the duration of fever, but there was no difference in duration of admission and x-ray deterioration.

PURPOSE: By analysing frequency and disease progression, this study aimed to investigate and predict the prognosis of mycoplasma pneumonia according to radiographic pattern. MATERIALS AND METHODS: We retrospectively reviewed plain chest radiographs of 230 patients in whom mycoplasm pneumonia had been serologically confirmed.Their age ranged from two months to 14 years and two months, and 203(88.3%) were younger than eight years. Radiographic patterns were classified as air space consolidation, bronchopneumonic, interstitial pneumonic ordiffuse mixed infiltrating type. The radiologic resolution period for each type was analysed by the resolution of symptoms and normalization of radiologic findings. RESULTS: The bronchopneumonic type, which was the most common, was seen in 82 patients (35.6%), airspace consolidation in 58 (25.2%), interstitial in 55 (23.9%), and diffuse mixedin 22 (9.57%). In thirteen patients (5.7%), chest radiographs were normal, though the clinical and radiologic resolution period for each type was variable. The mean resolution period of the air space consolidation type was 14.5 days, bronchopneumonic, 7.6 days ; interstitial, 10.5 days, and diffuse mixed, 15.6 days. The airspace consolidation type needed the longest recovery period, exceeded only by the diffuse mixed type. CONCLUSION: The bronchopneumonic type was the most common radiographic pattern of mycoplasma pneumonia. The prognosis of the airspace consolidation type seems to be poorest, since this required the longest recovery period.
