Abstract

Inflammatory myofibroblastic tumour (IMT) is a kind of rare soft tissue tumour. The most commonly affected organ reported is the lung. However, IMT can occur in any organ of the body. Although abdominal IMTs have been reported, retroperitoneal tumours are exceedingly rare. We here present a case of a thirteen-year old boy with a huge retroperitoneal mass diagnosed as IMT. The tumor was excised completely and no recurrence was found one year after surgery.
