Inflammatory myofibroblastic tumor of mediastinum with esophageal and bronchial invasion: a case report and literature review.

We report a case of inflammatory myofibroblastic tumor of the posterior mediastinum and describe radiological features demonstrated on fluoro-esophagogram, computed tomography and positron-emission tomography. Fluoroscopic video-esophagogram was remarkable for an unusual polypoid lesion associated with partial esophageal obstruction and features of secondary achalasia. Computed tomography (CT) examination demonstrated coarse calcifications and air pockets, while unusual clinical features included an intraluminal esophageal lesion and local recurrence with endobronchial lesion.
