PURPOSE: To evaluate the chest radiographic findings of rickettsial disease including murine typhus and tsutsugamushi disease in Chunchon. MATERIALS & METHODS: Chest radiographic films of 81 cases diagnosed as rickettsial disease(55 cases of tsutsugamushi disease, 26 cases of murine typhus) by immunofluorescence test were retrospectively analyzed. RESULTS: Main serotypes of Rickettsia tsutsugamushi were Gilllain and Karp. Incidence rate of tsutsugamushi disease was 2.1 times greater than that of murine typhus. Chest radiographs were abnormal in 63.6% of tsutsugamushi disease, and in 30.8% of murine typhus. Radiographic findings were Kerly's B line, reticu-Ionodular densities, hilar enlargement, pleural effusion, and splenomegaly in both entities, but pulmonary consolidation was only found in tsutsugamushi disease. The patients with the abnormal radiographic findings were statistically well correlated with cardiomegaly(p<0.01) and azygos engorgement(p<0.05), as compared to the patients with normal radiographic findings. CONCLUSION: Radiographic findings of both murine typhus and tsutsugamushi disease were interstitial pattern. But the chest radiographs in patients with tsutsugamushi disease showed more severe pattern with higher rate of abnormality.
