Magnetic resonance imaging of heterotopic gray matter.
Heterotopic gray matter was detected by means of magnetic resonance imaging in a 3-year-old girl with left hemiparesis and atonic seizures. In the inversion recovery sequence, a large area of decreased signal intensity was noted in the right centrum semiovale and differentiation of the right basal ganglia was not clear. We speculated that the brain malformation in our patient occurred at ten weeks conceptional age.
