Abstract：Objective To explore the CT manifestations of pneumonia-type carcinoma of the lung(PTCL) and to discuss related diseases that need to be identified together with PTCL.Methods CT manifestations of 17 patients with PTCL confirmed by percutaneous biopsy, fiberoptic bronchoscopy and sputum exfoliated cytology examination and surgery were retrospectively analyzed.Results Among the 17 cases of PTCL, there were 14 cases of adenocarcinoma, 2 cases of adenosquamous carcinoma and 1 case of bronchioloalveolar carcinoma. CT manifestations included ground-glass density(13 cases), small nodular shadows(15 cases), consolidation shadows(17 cases), air bronchogram (16 cases), dead branch signs(14 cases), angiogram signs(12 cases),pleural thickening(16 cases), cavitation(13 cases), honeycomb signs(5 cases), crazy paving signs(9cases),lymphadenectasis in the mediastinum and/or hilus pulmonis (13 cases), bone destruction(4 cases), and hydrothorax(11 cases). Among the 12 cases who had undergone CT enhancement scan, 7 cases were obviously enhanced and 5 cases were slightly enhanced.Conclusions PTCL is likely when CT manifestations include ground glass density signs, multiple nodules, dead branch signs, cavitation and honeycomb signs, crazy paving, pleura thickening near the mediastinal pleura, or when the consolidation areas of the lung are obviously or slightly enhanced after CT enhancement scan and there are angiography signs or peripheral distribution, or when the above symptoms are accompanied by irritating cough, white mucus, blood in phlegm, and an increase of tumor markers.
