Inflammatory pseudotumor (plasma cell granuloma) of the lung is an uncommon nonneoplastic tumor of unknown origin. This tumor typically manifests as a solitary, peripheral, and sharply circumscribed mass. Multiple lesions are seen in about 5% of cases. Resection is recommended for both diagnosis and treatment, and this tumor does not generally recur after complete resection. Here, we report a case of recurrent inflammatory pseudotumor after complete resection; the recurrence was detected as a series of bilateral consolidated lesions with an internal air bronchogram. This is an unusual finding with regard to inflammatory pseudotumors.
