Differential diagnosis of premature brain cysts

Approach to differential diagnosis of premature brain cysts:

  • Subependymal cyst from in-utero neonatal intraventricular hemorrhage grade I is located in the germinal matrix
  • Choroid plexus cyst is located in the choroid plexus
  • Connatal cyst is located just lateral to the superolateral angles of the anterior horns of the lateral ventricles
  • Periventricular leukomalacia cavitation usually occurs as a bilateral process
  • Periventricular hemorrhage cavitation usually occurs as a unilateral process
