[SPECT (single photon emission computed tomography) findings in 4 cases of neuronal migration disorders].
We report SPECT findings in four children with various types of neuronal migration disorders. SPECT of a patient with heterotopia showed a protrudent abnormal shadow into the centrum semiovale, the density of which was same as that of normal gray matter. The function and the metabolism of heterotopia appear same as those of the normal gray matter. ⋯ These pathologies may be related to our SPECT findings. SPECT of a patient with cortical dysplasia showed extensive lesions of decreased blood flow which was more wide spread than abnormal lesions detected by MRI. SPECT may be more sensitive than MRI to detect cortical dysplasias.
