Abstract

This report presents the "penumbra sign" of Brodie's abscess in a 17-year-old boy. The lesion was located in the proximal metaphysis of the left tibia. Histologic and microbiologic confirmation of the diagnosis was made. A "penumbra sign" on non-contrast enhanced T1-weighted magnetic resonance images is a helpful diagnostic sign of Brodie's abscess.
