Patient: Description of the condition (time of onset, main symptoms, hospital visited, etc.): CT showed: A nodular shadow was seen in the lingual segment of the upper lobe of the left lung, with a size of about 1.8×1.8 cm, and an irregular bronchial shadow was seen within it, and the nodular shadow was connected to the adjacent pleura, and an irregular small group shadow was seen above it, and a bronchial shadow was seen within it, and the bronchi were still open in each lobe segment. Lymph nodes, bilateral pleural cavity did not see fluid. The doctor suggested to review the patient after anti-inflammatory treatment and to exclude the occupancy. The doctor recommended that the patient should be reviewed after anti-inflammatory treatment, and the occupancy should be excluded. I would like to ask the doctor to help me find out what this disease is. Is this a good treatment? (Mixed feelings, nervous.) Thank you, doctor. The most important thing is that it is very difficult to determine the size of the nodule from the image, and it needs to be combined with enhanced CT, preferably with PETCT, as well as tumor markers and tuberculosis-related tests. Such a nodule is usually difficult to improve in the short term with anti-inflammatory therapy, but if it continues to increase in size, further investigations are recommended, and of course the most fundamental examination is to obtain pathological results. For lesions close to the pleura, the pathology is usually obtained by puncture or surgery. In cases where malignant lesions cannot be excluded, our surgeons do not recommend puncture because it will cause contamination of the needle tract and make the tumor spread further, and we prefer surgery.
