Pulmonary Honeycombing:HRCT Appearances,Pathological Fundament and Its Clinic Value / 实用放射学杂志

ABSTRACT

Objective To study HRCT appearances,clinic value and pathological fundament of the pulmonary honeycombing.Methods 60 patients including three groups with pulmonary honeycombing underwent HRCT scan.The comparative study of HRCT-pathology was done in 6 pulmonary postmortems with honeycombing.Results On HRCT images,honeycombing cysts were round-like with air inside,the cyst walls included remains of pulmonary inherent components and hyperplastic fibrotic tissue in pathology.The diameter of cysts was small,58 cases of them belonged to small group(90.6%).The distribution of lesions was mainly at lower(47cases,71.9%)and peripheral lung zone(52cases,81.3%),but there were differences in different type of the diseases.The cysts might become larger and it is impossible to recovery.Conclusion The honeycombing cysts appear as cystic cavities arranging as multiple layers,the cystic walls consist of different tissues in pathology,that are the manifestations of the end-stage of pulmonary fibrosis.HRCT appearances in different patients in three groups were different.
