A Case of Pulmonary Inflammatory Pseudotumor: Recurrence Appearing as Several Consolidative Lesions after Complete Resection

Abstract

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.
