Inflammatory myofibroblastic tumor (IMT) is a rare tumorous lesion that presents as a solitary nodule. Complete surgical resection is the standard treatment. However, due to its rarity, the optimal therapeutic strategy for multiple IMTs has not been defined. A 32-year-old man was referred to our hospital for evaluation of multiple pulmonary nodules. On computed tomography (CT) scan of the chest, there were a 3.0 x 1.7 cm mass with heterogeneous enhancement in the left upper lobe and multiple small nodules bilaterally. We performed wedge resection of the mass, and histopathology revealed IMT. He was treated with oral corticosteroids. The clinical and radiologic responses were so excellent that a CT scan showed complete resolution 1 month after the initiation of corticosteroid therapy. These observations suggest that corticosteroids may be the way to treat bilateral multiple IMT of the lung.
