Abstract
Objective To study the image features and pathologic basis of pneumonia type carcinoma of lung(PTCL). Methods The clinical,pathological and serial imaging materials of 30 cases of PTCL proved by pathology were retrospectively analyzed. The image features of PTCL were summarized. Results The pathological types of PTCL included bronchioalveolar carcinoma in 21 cases and adenocarcinoma in 9 cases. The main CT findings of PTCL in 33 cases were consolidation,included single lobar or segmental consolidation (n＝27,81.8%),multilobar consolidation (n＝6,18.1%). With in consolidation demonstrated lower density with angiogram sign (n＝21,63.6%),and air bronchogram(n＝27,81.8%) with leafless tree sign (n＝18,54.5%);Outside of consolidation showed honeycomb sign (n＝27,81.8%),ground glass shadow (n＝21,63.6%),multinodules (n＝6,18.1%).The other findings included little pleural effusion (n＝3,9.1%),enlarged mediastinal lymph node (n＝3,9.1%). Conclusions The imaging features of PTCL are varied, but the imaging dynamic changes of PTCL are of relative characteristic. Key words: Lung; Pulmonary carcinoma; Radiology
