[Desmoid tumor of the thoraco-abdominal wall characterized with 18F-fluorodeoxyglucose PET/ CT scan. Correlation with magnetic resonance and bone scintigraphy. Review of the literature]

Abstract

Desmoid tumours are uncommon benign tumours but with aggressive behaviour, resulting from the proliferation of well-differentiated fibroblasts. Clinically, they present as a painless firm soft tissue mass. They can be solitary or multiple and have potential infiltrative capacity. When planning treatment, it is important to assess the correct tumour extent to permit curative radical surgery minimizing possible local recurrence. Different imaging techniques help to characterise these tumours. At present, magnetic resonance is the tool of choice for studying these tumours. The role of nuclear medicine techniques, such as bone scintigraphy, or more recently FDG-PET, has not been defined in the evaluation of these neoplasms. We present the case of a patient with a desmoid tumour of the abdominal-chest wall and we review the related literature.
