Methods Twenty-two cases of pneumonitic pseudotumor confirmed by surgery and pathology were collected, and their imaging features were analyzed. Results The results showed that it was of great significance for the diagnosis of pulmonary inflammatory pseudotumor due to signs such as flat ankle, apical peach syndrome, localized thickened pleural adhesions, long burr, small cavity, and even enhancement.
