Overview

  • Pineal teratoma is an uncommon extra-axial intracranial cancer, which can have a bewildering variety of components and thus a wide range of appearances.[1]
  • Pineal teratoma may be classified into three subtypes: mature, immature, and mature with malignant transformation.
  • Mature teratomas are benign, mature, well-differentiated cystic lesions; whereas immature teratomas are poorly differentiated lesions with solid components and malignant transformation.[2]
  • On other occasions, mature teratomas contain elements that undergo malignant transformation (most commonly squamous components).
  • Fat
  • Cystic spaces due to mucous production or other exocrine products
  • Soft-tissue from any part of the body
  • Calcification, including teeth
