Purpose
To describe a common pattern seen of patients with decreased volume of the white matter associated with severe psychomotor impairment.
Methods and Materials
Nine 0.5 Tesla, magnetic resonance examinations of eight patients with severe psychomotor impairment were collectively evaluated. Axial T1WI, axial T2WI, sagittal T1WI coronal T1WI and coronal T2WI were compared.Patients:FC, male scanned at 8 months and 19 months oldSWVD, 17 month old maleMB, 2 year old maleAM, 3 year old femaleLP, 6 year old maleFG, 6 year old maleGG, 9 year old maleMC, 22 year old female
Results
Findings:1. In all cases, the lateral ventricles appear butterfly-shaped on coronal views at the level of the atria.2. Non-myelination in the juxtaventricular white matter3. Decreased volume of the posterior third of the corpus callosum4. Squaring of the posterior cap of the lateral ventricles5. Irregular contour of the ventricular walls6. The sylvian fissures are deep and almost extend to the lateral ventricles.
Conclusion
The butterfly pattern results from a decrease of parietotemporal white matter and is seen of patients with a history of developmental psychomotor impairment.
