Abstract

Inflammatory myofibroblastic tumors (IMTs) of the neck are rare, with only a few patients reported in the literature. The present study discusses the clinical manifestations, radiographic characteristics and management of these tumors, with a focus on imaging modalities. A case of IMT of the neck is presented and the associated literature is reviewed. In total, seven patients in seven English‑language studies, including the present case, and one patient in one Chinese‑language study were found. On CT scans, all tumors appeared as soft‑tissue densities. Upon magnetic resonance imaging (MRI), all tumors displayed a heterogeneous hypointense‑isointense signal on T1‑weighted sequences and an isointense‑hyperintense signal on T2‑weighted sequences. All tumors showed enhancement on enhanced CT and MR images. The imaging features of the neck IMTs can be summarized as follows: i) When enhanced, the tumor displays enhancement on CT and MR images; ii) MRI is superior to CT scans in the differential diagnosis of this disease; iii) in general, the lesion displays a hypointense‑isointense signal on T1‑weighted sequences and an isointense‑hyperintense signal on T2‑weighted sequences; iv) due to the fibrous tissue in the tumor, delayed enhancement may be observed on gadolinium‑enhanced MR images; and v) due to its benign or intermediate features, the tumor is usually a well‑defined mass.
