Abstract
Inflammatory pseudotumor was a kind of rare benign tumor of the lung, whose incidence was only about 0.7% in all kinds of tumors of the lung. Multiple inflammatory pseudotumor in both lungs were rare, which were often misdiagnosed to metastatic tumor or disseminated pulmonary tuberculosis. The literature reports were scarce too. This report introduces one case of multiple inflammatory pseudotumor in both lungs that we met in clinical works, and discusses the diagnosis and treatment of it.
