Cystic pineal glands are a normal variant, appearing in 2.4% of MRI studies. These common findings show no change over time, with established criteria for normality.

Area of Science:

  • Neuroradiology
  • Neuroanatomy

Background:

  • The pineal gland is a midline endocrine structure.
  • Cystic lesions of the pineal gland can be incidental findings on neuroimaging.

Purpose of the Study:

  • To determine the frequency and imaging characteristics of cystic pineal glands.
  • To establish criteria for identifying normal variants of pineal cysts.

Main Methods:

  • Retrospective review of 500 consecutive magnetic resonance imaging (MRI) studies.
  • Analysis of cyst size, MRI appearance, and associated imaging signs.

Main Results:

  • Cystic pineal glands were identified in 2.4% of the reviewed cases.
  • Follow-up examinations showed no interval change in the cysts.

  • Specific size, MRI appearances, and signs were documented.

    • Conclusions:

    • Cystic pineal glands are a common normal variant.
    • The findings provide criteria to differentiate normal pineal cysts from pathological lesions.
