ABSTRACT
Objective To investigate the characteristics of multislice spiral CT in solitary pulmonary mucinous adenocarcinoma and its relationship with pathology. Methods The clinical data, CT characteristics and pathological features of 16 patients with solitary pulmonary mucinous adenocarcinoma confirmed by pathology from March 2010 to May 2018 were analyzed, and the number, distribution, size, shape, boundary, density, adjacent structure changes and intensifying performance were observed and compared with pathological results. Results The single lesion was distributed in the lung lobe in 16 cases, in the lower lobe in 13 cases, in the middle lobe in 1 case, and in the upper lobe in 2 cases, of which 12 cases were located under the pleura. There were 2 cases of central type and 14 cases of peripheral type. The longest diameter of tumor was 1.2- 3.0 cm, with an average of (2.1 ± 0.9) cm. Eleven lesions were round or approximately round, 5 lesions were irregular, 8 lesions had clear boundary, 6 lesions had irregular boundary and burr sign, 12 lesions had shallow or deep lobulation, 2 lesions had small vacuoles and 2 lesions had vascular aggregation. Multislice spiral CT plain scan showed that the density of lesions was lower than that of the same level muscle density. Enhanced scanning showed mild to moderate homogeneous or heterogeneous enhancement. Microscopic examination revealed that the cytoplasm of tumor cells contained large amounts of mucus and mucus was fluid. Most of the tumor cells were attached to the cell wall. Some of the tumor cells were floating in mucus and flowing with mucus. Conclusions If the tumor distribution and morphology is associated with the gravity factor, the enhanced scan is stripe like, and there is no invasion of the pleural, no pleural effusion and no metastasis when the tumor is large, and the solitary pulmonary mucinous adenocarcinoma should be highly suspected.
