Key Words: Inflammatory myofibroblastic tumor
A 1-year-old male infant was referred to our clinic for an intrathoracic mass lesion that have ensued after a severe upper respiratory tract infection and empyema 6 months ago. His chest X-ray was consistent with a right sided huge mass lesion (Fig. 1A)
. Magnetic resonance imaging of the thorax disclosed the dimensions of the paravertebral mass to be 5x5x17 cm (Fig. 1B). It was excised via a right sided thoracotomy and the pathological analysis was relevant with an inflammatory myofibroblastic tumor–indicating the elements making up the lesion (Fig. 2)
