Table 1C.

Magnetic resonance imaging (MRI) and head ultrasound (US) findings for nine preterm infants with seizures.

Subject MRI Findings US findings
A

  • Bilateral IVH + periventricular hemorrhagic infarct (left > right)

  • Ventriculomegaly

  • Edema of the basal ganglia and thalami bilaterally

  • Bilateral IVH + periventricular hemorrhagic infarct (left > right)

  • Ventriculomegaly
B

  • Occipital schizencephaly

  • Diffuse, mild increased echogenicity of periventricular white matter
C

  • Severe, symmetric white and grey matter injury of bilateral posterior temporal/parietal/occipital white and grey matter

  • Ventriculomegaly

  • Severely delayed sulcation

  • Poorly defined periventricular and cortical abnormalities

  • Ventriculomegaly
D

  • Bilateral IVH + right periventricular hemorrhagic infarct

  • Ventriculomegaly

  • Increased T1 signal in the ventrolateral thalami in keeping with hypoxic-ischemic injury

  • Bilateral IVH with echogenicity suggesting hemorrhagic infarct on the right and possibly the left

  • Ventriculomegaly
E

  • Bilateral IVH + periventricular hemorrhagic infarct (right > left)

  • Bilateral subdural hemorrhage

  • Ventriculomegaly

  • Bilateral IVH + periventricular hemorrhagic infarct (right > left)

  • Bilateral subdural hemorrhage

  • Ventriculomegaly
F

  • Bilateral subependymal hemorrhage

  • Mild ventriculomegaly

  • Numerous bilateral multifocal punctate enhancing T1 hyperintense white matter lesions in keeping with Candida microabscess

  • Resolving subependymal hemorrhages

  • Borderline left ventriculomegaly

  • Few parenchymal echogenic foci, non-specific in appearance
G

  • Bilateral subependymal hemorrhages

  • Increased T1 and decreased T2 signal in the ventrolateral thalami and basal ganglia in keeping with hypoxic-ischemic injury

  • Diffuse white matter injury

  • Bilateral subependymal hemorrhages

  • Echogenic thalami, non-specific in appearance
H

  • Extensive diffuse and focal white matter injury

  • Heterogeneity of the white matter
I

  • Left IVH grade II

  • Left frontal dysplasia

  • Left IVH grade II

  • Increased echogenicity of periventricular white matter bilaterally left >right

IVH indicates intraventricular hemorrhage (grade I, subependymal hemorrhage; grade II intraventricular hemorrhage; grade III intraventricular hemorrhage with dilatation of the ventricles).
