ABSTRACT

Objective ToexploreimagingfeaturesanddiagnosticvalueofCTonpulmonarycomplicationsafterhematopoietic stemcelltransplantation (HSCT).Methods ThoracicCTimagesoffiftyGfourpatientswithpulmonarycomplicationafter HSCT werecollectedandtheimagingfindingswereretrospectivelyanalyzed.Results Accordingtoclinicaldiagnosis,fiftyGfourpatientswere classifiedasfungalinfection (30cases),cytomegalovirus (CMV)pneumonia(6cases),bacterialpneumonia(5cases),diffusealveolar hemorrhage(DAH)(4cases),pulmonaryedema(2cases),idiopathicpneumoniasyndrome(IPS)(1cases),bronchiolitisobliterans (BO)(3cases)andbronchiolitisobliteransorganizingpneumonia (BOOP)(3cases).OnCT,thefungalinfectionappearedasscattered nodule,consolidationorgroundglassopacity,andaircrescentsignwasseeninsixcases.Thebacterialpneumoniaappearedaspatchy, lineandgroundglassopacityorlargeconsolidation.TheDAHappearedasdiffuseexudate,alveolarnodularorconsolidation.Thepulmonary edemaappearedastypical"batwing"pattern.TheCMVpneumoniaandIPSappearedasdiffusegroundglassopacity,nodular,consolidation oratelectasis.TheBOshowedlargegroundglassopacitywithdilatedbronchioles,whiletheBOOPappearedaspatchyconsolidation andgroundglassopacity.Conclusion Patientsafter HSCT mayhavepulmonaryinfectiousandnonGinfectiouslesions.CTfeatures combinedwithclinicalsymptomsandpostGtransplantationtimecanhelptoevaluatecomplicationsaccuratelyandreducemortality.
