Abstract:
Objective:To investigate the CT imaging features and Pathological basis of pulmonary primary mucinous adenocarcinoma(PPMA).Methods:Retrospective analysis clinical and imaging data of 32 patients with PPMA confirmed by surgery,bronchoscopy or CT guided biopsy.To observe the shape,location,intralesional and peripheral conditions,enhancement and metastasis of the tumors.Results:32 cases of PPMA were single lesions 7 cases of central type,25 cases of peripheral type.There were 20 cases located in the lower lobes of both lungs,6 cases in the middle and upper lobes of the right lung and 6 in the upper lobes of the left lung.There were 27 cases of nodular mass type and 5 cases of pneumonia type.In contrast-enhanced scan,mild enhancement was found in most cases,and moderate enhancement was found in 2 cases.Metastasis occurred in 9 cases,including hilar and mediastinal lymph node metastasis in 5 cases,liver metastasis in 1 case,intrapulmonary metastasis in 3 cases and bone metastasis in 2 cases.Nodular mass PPMA showed lobulation sign in 11 cases,burr sign in 5 cases,halo sign in 9 cases,pleural indentation sign in 4 cases,cavity or vacuole sign in 6 cases.Among 32 cases of lung mucinous adenocarcinoma,10 cases had bronchoinflatable sign and 18 cases had angiographic sign.Both signs appeared in 5 cases of pneumonic PPMA.Conclusion:The clinical symptoms of PPMA are not typical,the CT signs have certain specificity,and each CT sign has corresponding pathological basis.CT examination can improve the early diagnosis of lung mucinous adenocarcinoma.
