Common Fungal Strains On Patients With Hematologic Malignancies CT Manifestations Of Lung Infection

Objective: based on the combination of clinical symptoms and signs,emphatically analyzed,summarized different fungi strains lung CT signs of infection,in order to improve the diagnostic level.Methods: collected in February 2013 to December 2014,our hospital clinical data integrity,basic disease for hematologic malignancies and secondary pulmonary fungal infections are a total of 128 cases,including aspergillus 51 cases,5 cases with mucor,cryptococcus 8 cases,candida albicans cartesian pneumocystis 44 cases,20 cases.First diagnosis and treatment were performed after TOSHIBA16 row helical CT chest 10 mm thick scan and 1 mm thickness layer reconstruction,obtain and analyze the CT images,type,shape,number of analysis includes lesions,involving the scope,distribution,edge,the internal characteristics and the surrounding changes,and the imaging findings were compared before and after treatment.Results: different fungi strains: CT features of lung infection:(1)the aspergillus pneumonia lesions is given priority to with nodular consolidation,consolidation of the patch,lump,flake times,in the subpleural,mostly happens,scattered lesions,halo sign,wall nodule,air crescent sign occurrence rate is higher,the duality can be halo sign;Can be associated with pleural adhesions,pleural effusion,enlarged mediastinal lymph nodes;Did not see clusters or fusion,rare interlobular septal thickening,lung tissue pull,etc.(2)the mucor pneumonia: the subpleural fuzzy boundaries,edge nodes is coarse,lump,flake consolidation seen,most often happens,scattered,partly visible leaf,there can be a wall nodule and empty,halo sign and the halo sign appear rate is higher,pleural adhesions,pleural effusion,can have of mediastinal enlarged lymph nodes.Cryptococcal pneumonia(3): the subpleural parts for good hair,the lesion is given priority to with nodules,lump consolidation,margin often irregular,can be a lobulated,consolidation within the hole,part of the lesions have fusion trend,did not see wall nodule and air crescent sign,also can show the sprouts and millet sample blood sample line spread changes.(4): candida albicans pneumonia are multiple lesions,morphological diversity,can show the spot piece,nodules,rope,patchy consolidation and ground glass density,sprouts and millet,and so on,and often coexist,can see dizzy),can be seen in the consolidation of irregular hole,no wall nodule and air crescent sign,but with much viscera cartesian pneumocystis pneumonia infection(5): give priority to with diffuse ground glass density lesions,lesion area visible lobular centricity or gland bubble nodular shadows,patchy consolidation,reticular and rope,some cases of visible fusion patchy consolidation,can also see air bags,are the two lung involvement at the same time,some small subpleural affected cases,pleural effusion,pleural adhesions,mediastinal major lymph node is rare,did not see wall nodule,hollow,the halo sign.Conclusion: the incidence of different strains of CT manifestation of pulmonary fungal infection in each characteristic,CT in common fungal pulmonary infection has important practical value.
