title: New radiographic classification of bone involvement in pedal mycetoma.
abstract: OBJECTIVE
  The purpose of this study was to classify the pattern, extent, and severity of bone involvement in mycetoma of the foot.
  
  
  CONCLUSIONS
  In this classification, stage 0 indicates the presence of soft-tissue swelling without bone involvement. Stage I refers to the extrinsic pressure effects on the intact bones in the vicinity of an expanding granuloma. Stage II results from irritation of the bone surface without actual intraosseous invasion. Cortical erosion and central cavitation occur in stage III. If the disease spreads longitudinally along a single ray, stage IV is established; horizontal spread along a single row represents stage V. Multidirectional spread due to uncontrolled infection is classified as stage VI.
