Endobronchial Inflammatory Myoblastic Tumor (IMT)—A Sleeve to Solve the Issue

Inflammatory myoblastic tumors of the lung are rare benign lesions. Here we present the case of a 15-year-old boy with postobstructive pneumonia. Computed tomography of the chest revealed a mass in the left mainstem bronchus that was confirmed on bronchoscopy. A rigid bronchoscopy with core resection was performed. Findings on pathologic examination were consistent with an inflammatory myoblastic tumor. The initial core resection relieved his postobstructive pneumonia; however, repeat bronchoscopy a month later demonstrated recurrence of the lesion. The tumor was removed with a parenchymal-sparing sleeve resection. At 80 months of follow-up, the patient is without evidence of recurrence or stenosis.
