Cervical Sympathetic Trunk-Centered Inflammatory Myofibroblastic Tumor Complicated with Postoperative First Bite Syndrome

Abstract Inflammatory myofibroblastic tumors (IMTs) in the head and neck region are common, but those with sympathetic trunk involvement extremely rare. Here we present a case of cervical trunk-centered IMT which is also accompanied by ipsilateral carotid artery, internal jugular vein, vagus nerve involvement. The patient initially complained an episodic painful swelling on right side underwent surgery. Preoperative postoperative serum IgG4 level during 3-year follow-up time within normal limits. Immunohistochemical study tumor has revealed negativity to IgG4. Postoperative first bite syndrome (FBS) was observed. Surgery seems be first-line therapy IgG4-negative IMT.
