Embolization of a large progressive symptomatic desmoid tumor in the rectus muscle of a female patient with multiple sclerosis: a case report

Abstract

Introduction: Desmoid tumors are benign tumors, yet can lead to significant morbidity due to aggressive local expansions. Treatment starts with a wait-and-see policy, however, more aggressive treatments like broad margin resection surgery might be necessary in case of tumor progression.

Patients and methods: We report the case of a 26-year-old female with a symptomatic desmoid tumor in the left rectus muscle. The initial wait-and-see policy led to an increase in tumor size and progression of symptoms. Computed tomography (CT) angiography revealed a dominant arterial blood supply via a branch of the inferior epigastric artery. We then performed a super selective embolization of the dominant arterial blood supply, to avoid the need for broad margin resection.

Results: At three months follow-up, the patient was asymptomatic and magnetic resonance imaging (MRI) showed no residual tumor. At nine months follow-up, MRI scan reconfirmed the successful outcome.

Conclusions: Embolization of a primary supplying vessel of a desmoid tumor is a viable treatment option. However, scientific evidence remains limited and further research is mandatory for inclusion in evidence based treatment algorithms.
