title: Cortical dysplasia and obstetrical brachial plexus palsy.
abstract: We report 2 patients with obstetrical brachial plexus palsy, ipsilateral leg weakness, and contralateral motor cortical dysplasia. To our knowledge, this is the first description of such an association. In both cases, the diagnosis of obstetrical brachial plexus palsy was established clinically shortly after birth and later confirmed neurophysiologically. Motor cortex dysplasia was diagnosed by magnetic resonance imaging (MRI). The association of obstetrical brachial plexus palsy and contralateral motor cortex dysplasia, a condition known to produce congenital hemiparesis, raises the possibility that the cortical dysplasia was a predisposing factor for obstetrical brachial plexus palsy in these cases.
