Imaging features of myxoid soft-tissue tumours

Myxoid soft-tissue tumours are mesenchymal neoplasms, which are characterised by the production of abundant extracellular myxoid matrix. Imaging plays an important role in the diagnosis of these tumours as well as treatment planning. The imaging features as well as the clinical course for these lesions are highly variable, depending on both the anatomical location of the tumour and the histopathological subtype. This article, illustrated by histopathologically proven cases from our tertiary referral soft-tissue sarcoma centre, reviews the spectrum of imaging findings and characteristic signs seen with different types of benign and malignant myxoid soft-tissue neoplasms.
