The magnetic resonance (MR) imaging features of Brodie abscess have not yet been fully evaluated. Ten patients with Brodie abscess, eight of long bone and two of vertebra, were studied with MR imaging. Long bone abscess had a characteristic “target” appearance with four layers: (a) a center with low signal intensity on T1‐weighted images and high signal intensity on T2‐weighted and STIR (short‐inversion‐time inversion recovery) images, (b) an inner ring isointense to muscle on T1‐weighted images and with high signal intensity on T2‐weighted and STIR images, (c) an outer ring hypoin‐tense on all images, and (d) a peripheral halo hypointense on T1‐weighted images. In six of eight cases, a soft‐tissue mass was found. The two vertebral abscesses had a less specific appearance, with low signal intensity on T1‐weighted images and high signal intensity on T2‐weighted and STIR images. Only the peripheral halo was clearly identified in both cases.
