We reported a case of Brodie's abscess which developed unusual patterns with penetration of the epiphyseal plate of the distal tibia. A thirteen-year-old boy was referred to our hospital complaining of mild pain and swelling of the left ankle.
The roentgenography of the left tibia disclosed a radio-lucent lesion which was surrounded by a clear osteosclerotic margin. The lesion existed in the metaphysis and epiphysis with penetration of the epiphyseal plate of the distal tibia. The C-reactive protein value and erythrocyte sedimentation rate were normal.
The diagnosis was made by a needle biopsy of the lesion with aspiration of pus. The bacteriological examination revealed staphylococcus aureus. Surgery with curettage and bone graft including the epiphyseal plate resulted in it healing and no deformity nor limb length-discrepancy was recognized.
