Summary

Tuberous sclerosis complex (TSC) in newborns often presents with seizures, not typical signs. This highlights seizures as a key indicator for diagnosing TSC in neonates, even without other classic symptoms.

Area of Science:

  • Neurology
  • Genetics
  • Pediatrics

Background:

  • Tuberous sclerosis complex (TSC) is a rare genetic disorder affecting multiple organ systems.
  • While TSC is known to cause tumors and affect the brain and heart, its presentation in neonates is not well-documented.
  • Neonatal seizures are rarely linked to TSC in existing literature.

Purpose of the Study:

  • To describe the presentation of TSC in neonates.
  • To highlight neonatal seizures as a significant, yet underrecognized, early sign of TSC.
  • To discuss neuroimaging findings in neonates diagnosed with TSC.

Main Methods:

  • Case report of two neonates diagnosed with TSC.
  • Review of clinical presentation, focusing on seizures.
  • Analysis of neuroimaging findings in the affected neonates.

Main Results:

  • Both reported cases presented with neonatal seizures as the primary symptom.
  • Traditional stigmata of TSC were absent or not prominent in the neonatal period.
  • Neuroimaging revealed findings consistent with TSC in both infants.

Conclusions:

  • Neonatal seizures should be considered a crucial presenting feature of Tuberous Sclerosis Complex.
  • Early recognition of seizures in neonates can lead to timely TSC diagnosis, even without classic physical signs.
  • This underscores the importance of considering TSC in the differential diagnosis of neonatal seizures.
