Abstract：Objective To investigate the pathological and clinical features of lung invasive mucinous adenocarcinoma in order to reduce the misdiagnosis and missed diagnosis rates. Methods Clinical data of one patient with lung invasive mu-cinous adenocarcinoma in our hospital was retrospectively analyzed. Results A 74-year-old female patient complained of hav-ing cough, expectoration and anhelation more than half a year, and fever more than half a month. Chest CT showed bilateral multiple pulmonary cavity and nodules, so she was misdiagnosed as having pulmonary abscess in Emergency Department. She had a variety of antibiotics and the treatment results were not satisfactory. CT showed that the lesion continued to progress, then she was finally diagnosed as having lung invasive mucinous adenocarcinoma by surgical biopsy. Although supporting treat-ment and traditional Chinese medicine were used, the disease progressed in the 9-month follow-up, accompanied by multiple lymph node metastasis and respiratory failure. Conclusion Multiple pulmonary cavity and nodules are not only the main per-formances of pulmonary infectious diseases but can also be observed in certain types of pulmonary carcinoma. Repeated chest CT after treatment should be performed. Early biopsy may be helpful to diagnosis when CT image shows signs of deterioration.
