High-resolution CT image characteristics of lung nocardiosis in patients with normal immune function
Abstract：Objective To investigate the high-resolution CT image characteristics of lung nocardiosis in patients with normal immune function in order to make early diagnosis.Methods The CT image features of 35 patients with lung nocardiosis were retrospectively analyzed,in whom,there were 20 females and 15 males, with age range being 49~80 years (average 61 years). All the patients had no history of immunosuppressive agents therapy and any immunosuppressive diseases. The traditional biochemical reaction experiments combined with total cell fatty acid gas chromatography (GC) analysis were used to determine the type of infection bacteria. Moreover all the patients underwent high resolution CT scanning.Results CT images showed pulmonary consolidation region in all the cases, with nodules and/or ground glass opacities,which distributed according to lobuli pulmonum,moreover,which also showed air bronchus sign,thickened wall and enlarged lumen of bronchioles in 35 patients.Besides there were multiple nodules with cavities and the diameter of nodules was larger than 1cm in 8 patients.Conclusion In normal immunocompetent patients with lung nocardiosis,the opacity, nodule and ground glass opacity are main features of CT images,and cavity is not a common finding.Therefor,if cephalosporin is not effective,the diagnosis of nocardia pneumonia should be considered.
