CT and MRI appearances of cardiac pseudotumours.

Cardiac anatomic variants, vascular abnormalities and non-neoplastic mass lesions may be misinterpreted as tumours, potentially leading to inappropriate intervention. This article discusses the complementary role of multi-detector computed tomography and magnetic resonance imaging in the work-up of suspected masses. The cross-sectional imaging appearance of common or distinctive anatomic variants and pseudotumours, including 'don't touch' lesions, are reviewed.
