PURPOSE: To evaluate the feasibility of using chest radiography to differentiate between three different etiologies of pulmonary edema. MATERIALS AND METHODS: Plain chest radiographs of 77 patients, who were clinically confirmed as having pulmonary edema, were retrospectively reviewed. The patients were classified into three groups: group 1(cardiogenic edema : n=35), group 2(renal pulmonary edema : n=16) and group 3(permeability edema :n=26). We analyzed the radiologic findings of air bronchogram, heart size, peribronchial cuffing, septal line, pleural effusion, vascular pedicle width, pulmonary blood flow distribution and distribution of pulmonary edema. In a search for radiologic findings which would help in the differentiation of these three etiologies, each finding was assessed. RESULTS: Cardiogenic and renal pulmonary edema showed overlapping radiologic findings, except for pulmonary blood flow distribution. In cardiogenic pulmonary edema(n=35), cardiomegaly(n=29), peribronchial cuffing(n=29), inverted pulmonary blood flow distribution(n=21) and basal distribution of edema(n=20) were common. In renal pulmonary edema(n=16), cardiomegaly(n=15), balanced blood flow distribution(n=12), and central(n=9) or basal distribution of edema(n=7) were common. Permeability edema(n=26) showed different findings. Air bronchogram(n=25), normal blood flow distribution(n=14) and peripheral distribution of edema(n=21) were frequent findings, while cardiomegaly(n=7), peribronchial cuffing(n=7) and septal line(n=5) were observed in only a few cases. CONCLUSION: On plain chest radiograph, permeability edema can be differentiated from cardiogenic or renal pulmonary edema. The radiographic findings which most reliably differentiated these two etiologies were air bronchogram, distribution of pulmonary edema, peribronchial cuffing and heart size. Only blood flow distribution was useful for radiographic differentiation of cardiogenic and renal edema.

PURPOSE: To evaluate the plain chest radiographic findings of smoke inhalation. MATERIALS AND METHODS:Our study included 72 burn patients who had suffered smoke inhalation. On admis-sion,all underwent serial portable chest AP radiography. We retrospectively reviewed the plain chest radi-ographs taken between admission and pootburn day five, evaluating the pattern, distribution, and time onset of direct injury to the respiratory system by smoke inhalation. The lesions were also assessed for change. RESULTS: In 16 of 72 patients (22%), abnormal findings of direct injury to the respiratory system by smoke in-halation were revealed by the radiographs. Abnormal findings were 15 pulmonary lesions and one subglottic tracheal narrowing. Findings of pulmonary lesions were multiple small patchy consolidations (10/15), peri-bronchial cuffing (8/15), and perivascular fuzziness (6/15). Patterns of pulmonary lesions were mixed alveolar and interstitial lesion (n=9), interstitial lesion (n=5), and alveolar lesion (n=1). No interlobular septal thicken-ing was observed. Pulmonary edema was distributed predominantly in the upper lung zone and perihilar re-gion, with asymmetricity. Its time of onset was within 24 hours in 13 cases, 24 -48 hours in two cases, and 48 -72 hours in one. Five of 16 patients progressed to ARDS. CONCLUSION: Chest radiographs showed that pulmonary lesions caused by inhalation injury were due to pul-monary edema, which the pattern of which was commonly mixed alveolar and interstitial.

The typical radiographic findings of pulmonary edema from the increased hydrostatic pressure shows centrally localized consolidation, which is known as a "butterfly or bat's wing" pattern. These terms describe the anatomic distribution of edema that uniformly involve the hilum and medulla of the lung but not the peripheral region of the lung parenchyma (cortex). We present a case of butterfly wing-like pulmonary edema on a chest radiograph by mitral regurgitation due to an idiopathic chordal rupture.

PURPOSE: To describe plain radiographic and thin-section CT findings of hematogenous candida pneumonia in major burn patients. MATERIAL AND METHOD: We reviewed nine cases of hematogenous candida pneumonia in major burn patients who had positive blood culture for candida and findings of pneumonia on plain chest radiograph. On five of nine cases, thin-section CT was done. We evaluated retrospectively nine cases for onset, the pattern, distribution, and size of lesions on plain chest radiograph and thin-section CT. RESULTS: On plain chest radiograph, randomly distributed 2-10mm nodules were seen in six cases(66%) and randomly distributed 10-15mm consolidations in remaining three cases{33% ). Lesion occured in 11th to 75th post-burn day{average, 34th post-burn day). Other findings were cardiomegaly in three cases, atelectasis in three cases, and pulmonary edema in one case. Thin-section CT showed variable shaped subpleural nodules in all five cases. The size of nodules were 1-5mm in two cases(40%) and 5-10mm(60% ) in three cases. Feeding vessel signs were seen in two cases. Other findings were atelectasis in three cases, cardiomegaly in three cases, ground-glass opacity and interlobular septal thickenings by pulmonary edema in two cases. CONCLUSION: Plain chest radiographic findings of hematogenous candida pneumonia in major burn patients are randomly distributed nodules or consolidations of variable size. Thin-section CT findings are variable shaped subpleural nodules less than 1 cm.

5.Pulmonary Complications in Major Burn Patients: Differences in Radiologic and Clinical Findings between Inhaled and Non-inhaled Burn.
Journal of the Korean Radiological Society 2003;48(5):407-412
PURPOSE: To analyze differences in the radiologic and clinical findings of pulmonary complications between an inhalation and non-inhalation group of major burn patients, and to apply the findings to the specific diagnosis of pulmonary complications. MATERIALS AND METHODS: This study involved 45 major burn patients (18 with inhalation injury, and 27 without) in whom pulmonary complications ensued. Follow-up studies were based on chest radiographs obtained between initial burn day and postburn (PB) 57 (mean, day 27). Types, times of onset, underlying causes, and changes at follow-up study of pulmonary complications between the inhalation and the non-inhalation group were assessed. RESULTS: In the inhalation group, the most frequent complication was air-borne pneumonia (n=7, 39%); others were hydrostatic pulmonary edema (n=5, 28%), ARDS (n=5, 28%), atelectasis (n=5, 28%), inhalation pneumonitis (n=3, 17%), pleural effusion (n=3, 17%), and hematogenous pneumonia (n=1, 6%). In the non-inhalation group, airborne pneumonia (n=8, 30%) was also the most common complication; other were hydrostatic edema (n=6, 22%), ARDS (n=5, 19%), atelectasis (n=5, 19%), pleural effusion (n=5, 19%) and hematogenous pneumonia (n=2, 7%). The average times of onset were as follow: for airborne pneumonia, PB day 13.1 (range, 5-27) in the inhalation group, and PB day 21.7 (10-49) in the non-inhalation group; for hematogenous pneumonia, more than one month, regardless of inhalation; for ARDS, PB day 4.9 (2-15) and PB day 13 (7-20) in the inhalation and non-inhalation group, respectively; and for inhalation pneumonitis, PB day 1.7 (1-3). The most common probable cause of ARDS in the inhalation group was inhalation injury (3/5), and in the noninhalation group, sepsis (4/5). CONCLUSION: In major burn patients, pulnonary complications differed in terms of their onset time and causes between the inhalation group and the non-inhalation group. In such cases, awareness of the presence or absence of inhalation injury and the onset time of pulmonary complications is necessary if complications are to be specifically diagnosed.

6.Pulmonary Edema following Phenylephrine Intranasal Spray Administration during the Induction of General Anesthesia in a Child.
Yonsei Medical Journal 2005;46(2):305-308
Topical phenylephrine, an agent used to facilitate nasotracheal intubation and prevent nasal mucosal bleeding, can cause severe hypertension in some patients, secondary to its stimulation of alpha-adrenergic receptors. Moreover, a high incidence of pulmonary edema is found in patients whose phenylephrine administration is followed by treatment with beta-blocking agents. We report a case of acute pulmonary edema in a pediatric patient who developed severe hypertension after the inadvertent administration of a large dose of topical nasal phenylephrine, followed by beta-adrenergic antagonists (esmolol).

Chemical pneumonitis induced by nitric acid inhalation is a rare clinical condition. The previously reported radiologic findings of this disease include acute permeability pulmonary edema, delayed bronchiolitis obliterans, and bronchiectasis. In very few published rare radiologic reports has this disease manifested as acute alveolar injury; we report a case of acute chemical pneumonitis induced by nitric acid inhalation which at radiography manifested as bilateral perihilar consolidation and ground-glass attenuation, suggesting acute alveolar injury.

A 45-Year-old para 1-0-1-1 had submucosal myoma diagnosed by ultrasonogram and hysteroscopic examination. During 60 minutes hysteroscopic myomectomy, 8,000 ml of sorbitol-mannitol distention medium was used and 6,500 ml collected, resulting in a deficit of 1,500 ml. The patient received Ringer`s lactate 1,000 ml intravenously. Her urine output was 400 ml. Blood loss was 40 ml. After operation, hyponatremia(115 mEq/L) was developed and pulmonary edema was also diagnosed clinically at that time and later confirmed by chest radiograph. The judicious administration of diuretics and normal saline fluid replacement to prevent overcorrection to hypernatremia resulted in return of serum electrolytes to normal level and resolution of the pulmonary edema by postoperative day 1. We have experienced a case of pulmonary edema during hysteroscopic myomectomy with sorbitol-mannitol distention medium, which is presented with a brief review of literatures.

Laparoscopy is a surgical procedure used both for diagnosis and for various treatments. A rare but sometimes fatal complication of laparoscopy is pulmonary embolism with CO2 resulting in pulmonary edema. During laparoscopic gynecological surgery in a 29-year-old woman who had previously undergone lower abdominal surgery, the end-tidal CO2 suddenly increased from 40mmHg to 85mmHg and then decreased to 13mmHg with hemodynamic deterioration. These events are characteristic of a CO2 embolism. When this occurred, CO2 insufflation was immediately stopped and the patient was resuscitated. The patient's condition gradually improved with aggressive treatment, but the clinical course was complicated by bilateral pulmonary edema. This case of pulmonary edema was soon resolved with supportive management. The formation of a CO2 embolism during laparoscopy must be suspected whenever there is a sudden change in the end-tidal CO2. In addition, the possibility of pulmonary edema should be considered when a CO2 embolism occurs.
