• Pathogenesis and clinical features of abdominal desmoid tumours. • Emphasis on MRI in diagnosis, assessment of complications and disease follow-up. • Subtle imaging features raising suspicion of a DT. • Spectrum of imaging appearances.

Background: Abdominal desmoid tumours (DTs) are rare, benign fibromatous neoplasms occurring sporadically or in relation to familial syndromes. Despite lacking malignant potential, DTs cause significant morbidity and mortality via local invasion and compressive effects upon adjacent organs. DTs are notoriously challenging to diagnose and manage. Role of MRI: Non-ionising cross-sectional imaging has a particular role in assessing young patients that require long-term follow-up. MRI signal characteristics can provide additional information over CT and suggest potential behavioural and cellular properties. MRI Imaging Features: DTs occur in variable locations with a wide range of appearances. We aim to demonstrate common and rare locations within the abdomen, specific signal characteristics and enhancement patterns to look out for. Conclusion: MRI is a useful modality in the diagnosis of DTs, frequently in a young population. We provide examples of commonly overlooked imaging appearances.
