Pathology

Taylor dysplasia is determined histologically due to the presence of certain features such as  giant neurons, dysmorphic neurons with or without balloon cells . The latter further divides FCDT into two main subtypes .

  • type IIa: no balloon cells
  • type IIb: balloon cells present

See: Palmini classification and Blumcke classification.
