Fetal seizures: a case study.
BACKGROUND
A review of the literature and an extensive Medline search revealed that this is the first case report of fetal seizures diagnosed by ultrasound.


METHODS
A 23-year-old woman was found to have a fetus with bilateral choroid plexus cysts during a second-trimester ultrasound examination. Karyotype and alpha-fetoprotein level were normal. The cysts resolved, but idiopathic polyhydramnios was noted. Fetal testing beginning at 32 weeks revealed abnormal fetal behavior patterns on ultrasound and documented fetal seizures with rapid, repetitive limb movements noted on several occasions and lasting 30-60 seconds. Similar movements continued after birth as tonic-clonic seizure activity.


CONCLUSIONS
Qualitative changes in movement patterns are common in neurologically impaired fetuses. Ultrasound may be used to diagnose these neurologic abnormalities that can be connected with clinical outcomes. This will better prepare the parents and hospital staff members for delivery and may also decrease medicolegal risk for the obstetrician because the abnormal behavior predates the birth process.
