Deep neck fibromatosis after diskectomy and cervical fusion: Case series and review of the literature

OBJECTIVE. The objective of our study was to report head and neck deep fibromatosis as part of the differential diagnosis of a firm painful neck mass after cervical fusion and diskectomy. CONCLUSION. Although they are rare tumors, fibromatosis tumors or desmoid tumors should be considered in a patient with a painful neck mass; a history of cervical spine surgery; and MRI findings showing a large, avidly enhancing, heterogeneous mass adjacent to surgical hardware that is hyperintense on T2-weighted imaging.
