A rare benign tumor of the lung: Inflammatory myofibroblastic tumor - Case report

Abstract

A fifty year old lady who was operated for thyroid cancer two years ago and completed adjuvant therapy, underwent a computer tomography (CT) of the chest during her follow up. The CT showed a mass lesion in the right lung, located to the lateral segment of the middle lobe. There were no intrabronchial lesions on bronchoscopy. Positron emission CT (PET CT) showed a dense hypermetabolic mass located in the right middle lobe lateral segment and having malignant characteristics. A videothorascopic wedge resection was performed and the specimen was sent for frozen section, which showed no evidence of malignancy. Pathology report revealed an inflammatory myofibroblastic tumor (IMT). Since IMT is a rare benign tumor of the lung, we herein report this patient along with a discussion of the relevant literature. © 2013 Elsevier Ltd.
