Abstract
- We analysed chest radiographic findings of 81 serologically confirmed leptospirosis patients from ChonbukNational University Hospital, Cnonju Presbyterian Medical Center and Nam won Province Hospital from September,1987 to July, 1989. The results are as follows: 1. Incidence of chest radiographic abnormalities was 52'%(42 of 81patients) and incidence of pulmonary parenchymal lesions was 38%(31 of 81 patients) 2. The pulmonary lesionsoccurred 3-7 days after clinical onset in 28 cases(90%) and 1-2 days in 3 cases. 3. The radiographic patterns ofpulmonary lesions were multiple small nodular pattern(16/31, 52%), massive confluent consolidation pattern(9/31,19%), and diffuse interstitial pattern(6/31, 19%). 4. The radiogarphic patterns of pulmonary lesions showedchanges in following sequence. Type I, II, III and finally resolution or similar change. 5. The radiologicgradings, representing extent of pulmonary lesions were as follows; Grade I(13%), Grade II(19%), Grade III(16%),Grade IV(52%). 6. The pulmonary lesions were distributed bilaterally in 77% and were predominant in rightlung(88%). There was very high tendency of peripheral occurance(91%) and distribution fo apec, perihilar regionand base of lung was 23%, 26% and 61%, respectively 6. 7. The resolution of pulmonary lesions was complete exceptfor expired cases and usually took less than 3 days (16%), 4-10 days in( 61%) and longer than 11days(13%) aftertheir appearance. And resolution took 2-4 days in Grade I cases, 3-10 days in Grade II cases, 4-11 days inGradeIII cases and 5-15 days in Grade IV cases. Thus the time of resolution was related to the extent of pulmonarylesions. The lesser the pulmonary lesion, the earlier the ressolution. 8. Extrapulmonary manifestation, such aspleurla effusion and cardiac enlargement was rare. In conclusion, radiogaphic manifestation provided usefulinformation about early diagnosis, prognosis evaluation & treatment of leptospirosis.
