Bilateral interstitial infiltration in chest radiography, which may be fine granular, reticular or of ground glass opacity, is the typical radiographic findings of Pneumocystis jiroveci pneumonia. Recently, atypical radiographic features, including cystic lung disease, spontaneous pneumothorax or nodular opacity, have been reported intermittently in patients with P. jiroveci pneumonia. We report the case of a 29-year-old woman with a transplanted kidney whose simple chest radiography and HRCT scan showed numerous miliary nodules in both lungs, mimicking miliary tuberculosis (TB). Under the presumptive diagnosis of miliary TB, empirical anti-TB medication was started. However, Grocott methenamine silver nitrate staining of a transbronchial lung biopsy tissue revealed P. jiroveci infection without evidence of TB. These findings suggest that even in TB-endemic area other etiology such as P. jiroveci as well as M. tuberculosis should be considered as an etiology of miliary lung nodules in mmunocompromised patients.

폐포자충 폐렴의 전형적인 전산화단층촬영 소견은 양측 폐에 미만성 혹은 다발성의 간유리 음영으로 잘 알려져 있지만, 드물게 다발성 폐 결절 형태로 나타날 수도 있다. 본 저자들은 다발성 골수종 치료로 인해 면역력이 저하된 환자의 양측 폐에 생긴 광범위한 간유리음영 및 이와 동반된 다발성 괴사성 늑막하 결절들이 경피적 폐생검을 통해 육아종성 폐포자충 폐렴으로 확진된 증례를 보고한다.
