title: Focal cortical dysplasia with calcification: a case report.
abstract: METHODS
  Focal cortical dysplasia (FCD) with calcification is rare. We presented a 13-year-old epileptic patient with FCD and calcification in the left frontal lobe. At age 24, the FCD lesion and the surrounding epileptogenic cortex and underlying subcortex were removed after chronic subdural electrode recording. Histological examination showed that the calcified lesion was not independent of the FCD lesion but located in the subcortical area of the FCD lesion. A neoplastic nature was ruled out for the lesion.
  
  
  CONCLUSIONS
  The pathophysiological mechanism involved in the coexistence of FCD and calcification is discussed.
