Abstract
|
|
|
|
The "penumbra sign" on an unenhanced T1-weighted image is a well-known characteristic of Brodie’s abscess, and this sign is extremely helpful for discriminating subacute osteomyelitis from other bone lesions. We present a case of primary bone lymphoma of the distal tibia mimicking subacute osteomyelitis with Brodie’s abscess in a 50-year-old woman. Initial radiographs and MRI showed a lesion in the distal tibia consistent with Brodie’s abscess with the penumbra sign. Histopathological examination of the surgical biopsy specimen confirmed the presence of a diffuse large B-cell lymphoma involving the bone.
