摘要


肺部隱球菌肺炎好發於免疫不足之病人,這是一種沒有菌絲的芽體真菌生長於土壤及鴿子糞便中,其罕見於免疫完備的病人。本文之目的在於分析肺部隱球菌肺炎於免疫不足及免疫完備的病人之電腦斷層影像。 閱檢12個已證明為肺部隱球症之病例,其電腦斷層發現為一個或多個結節(個數為十),一個或多個塊(個數為五),無數個小結節(個數為一)或肺實質化(個數為一),好發於近肋膜處(個數為十一)及下肺葉。(個數為八)。結節其邊緣為不明顯(個數為七),針刺狀(個數為七)及小葉狀(個數為四)。其中有一些有空氣氣管圖(個數為六),毛玻璃狀(個數為六)及空腔(個數為三)。 由於肺部隱球菌肺炎的無特殊臨床表徵。所以熟悉電腦斷層之表現,可以使肺部隱球菌肺炎之診斷更加容易,更加有效率。

Cryptococcus neoformans pneumonia occurs frequently in immunocompromised patients. The organism is a non-mycelial budding yeast found in the soil and in pigeons droppings. It is rare in immunocompetent patients. The aim of this study was to analyze computed tomography (CT) findings of pulmonary cryptococcosis in both immunocompromised and immunocompetent subjects. Twelve patients of proved pulmonary cryptococcosis were reviewed. Their CT findings were pulmonary nodules (n=10), masses (n=5), micronodule (n=1), consolidation (n=1) with subpleural location (n=11), and lower lobe predilection (n=8). The margin of the nodules were ill-defined (n=7), spiculated (n=7) and lobulated (n=4). Some of them had air-bronchogram (n=6), halo sign (n=6) and cavitation (n=3). The clinical picture of pulmonary cryptococcosis is non-specific. Therefore familiarity with the CT findings can make the diagnosis of pulmonary cryptococcosis earlier and easier.
