Association of trisomy 9p and band heterotopia.
Patients with the trisomy 9p syndrome and CNS abnormalities have been poorly assessed. We report a patient with trisomy 9p who showed band heterotopia on MRI. Abnormal neuronal migration is sufficiently frequent in patients with the trisomy 9p syndrome that brain MRI should be routinely considered in all patients with this syndrome.
