A Hypervascular Inflammatory Myofibroblastic Tumor in the Mediastinum Resected Completely Following Embolization of the Feeding Vessels

Abstract

Inflammatory myofibroblastic tumors (IMTs) are rare tumors of intermediate malignant potential that can occur anywhere in the body. We describe an interesting case of a hypervascular IMT in the mediastinum that could be resected completely following embolization of the feeding vessels. A 17-month-old girl with complaints of cough and fever for 3 months was referred to our hospital. Computed tomography (CT) scan showed a large mass in the right hemithorax that shifted the mediastinum to the left. Primary excision was considered but not performed because there was very active capsule wall bleeding due to the hypervascular tumor. After embolization of the feeding vessels, successful complete resection was carried out. Approximately 6 weeks after the operation, follow-up CT scan showed no evidence of recurrent disease. Preoperative embolization is a good option for performing complete resection of hypervascular IMTs that could reduce the recurrence rate.
