Differential diagnosis of Subependymal heterotopia in fetuses (SEH)

US MRI T1 MRI T2 Further useful information
Subependymal heterotopia Periventricular nodules:

  • - Hyperechoic

  • - Hypointense

  • - Often not detected

 Hypointense SEH could be associated with other brain anomalies
Tuberous sclerosis Periventricular nodules:

  • - Hyperechoic

  • - Often not detected

 Hyperintense Hypointense

  • - Often associated with cardiac rhabdomyomas

  • - Family medical history is usually helpful
Subependymal Hemorrhage (early subacute) Periventricular lesions:

  • - Hyperechoic

  • - Typical US evolution

 Hyperintense Hypointense Often associated with intraventricular hemorrhage and hydrocephalus
