Computed tomography and magnetic resonance imaging scans are often required to characterise an adrenal lesion according to its size, heterogeneity, content, and enhancement pattern. This report is of a diagnostic dilemma, in which a chronic expanding haematoma of the adrenal gland closely mimicked adrenal malignancy. The patient underwent computed tomography scan for an unrelated condition, and was incidentally found to have a large heterogeneous right adrenal mass. The mass was resected and pathological examination showed a chronic expanding haematoma. Specific imaging features of this entity and other differential diagnoses, such as adrenal malignancy and adrenal haemangioma, are reviewed.
