Abstract
Objectjve To study the imaging,clinical and pathologic characteristics of primary pulmonary mucinous adenocarcinoma(PPMA)and their diagnostic value. Methods Seven patients with histopathologically or needle biopsy proved PPMA in the Affiliated Hospital of School of Medicine of Ningbo University from March 2011 to March 2014,were selected as study subjects,the imaging,clinical and radiographic data of the subjects were collected. All patients underwent CT plain scan, among them,4 patients underwent CT multi - phase enhanced scan,and 1 patient underwent MR plain scan and multi - phase enhanced scan. Imaging findings were analyzed and compared with clinical and pathologic findings. Results 7 patients had 9 lesions,among whom 4 patients had solitary nodule,1 patient had multiple nodule and 2 patients had nodular consolidation. Of the 9 lesions,8 lesions were located in peripheral areas or under the pleural membrane,another lesion occupied the whole of the left lower lobe. The maximum diameter of the lesions ranged from 0. 5 to 17. 3 cm〔 mean value was(4. 9 ± 5. 0 ) cm〕. Hemorrhage and calcification were not found among all lesions in 7 patients;lobulated sign,vacuole sign and vascular convergence sign was found in 4 cases respectively;air bronchograms,bronchial cut - off sign,halo sign and pleural indentation sign was found in 3 cases respectively;spiculation,spiculate protuberance,crazy paving pattern,′ satellite′ disseminated nodules,angiogram sign and lung lobe distention was found in 2 cases respectively;3 cases had solid cystic lesions,solid components showed marginal distribution or internal scattered patchy distribution;MRI features of the lesion in 1 case showed〞 white lung sign〞,diffusion weighted imaging( DWI)of solid components showed obviously high signal and the apparent diffusion coefficient ( ADC ) value decreased obviously. 6 patients had histopathologically proved invasive mucinous adenocarcinoma of lung,among whom 1 was in stage Ia,1 was in stage Ⅱa,4 were in stage Ⅲa. Conclusjon PPMA had specific imaging and pathologic characteristics,understanding of the pathologic characteristics correctly can contribute to improving the image understanding. Lung consolidation patients with suspected pulmonary mucinous adenocarcinoma should undergo routinely MRI heavy T2WI and DWI.关键词
