Inflammatory myofibroblastic tumor of the mesentery: a clinical dilemma.

Although rare, extra-pulmonary inflammatory myofibroblastic tumors (IMTs) are becoming increasingly recognized. While surgical resection is currently an effective and accepted treatment for IMTs, the optimal management of unresectable or residual IMTs remains a clinical dilemma. We present the case of an incompletely resected IMT treated successfully with anti-inflammatory therapy alone, and describe the rationale for this approach.
