Common Peroneal Injury mistaken as Neuraxial Analgesia Complication after Normal Vaginal Delivery

“Lissencephaly”, a rare gene linked defective neuroblast migration disorder resulting in defective cortical lamination, abnormal gyral development and subcortical heterotropia. Advances in molecular genetics have led to the identification of lissencephaly gene on chromosome 17p13.3 and causing Type-1 Lissencephaly or miller Diecker syndrome where lissencephaly is severe in posterior brain region. Another X-linked gene Doublecortin (DCX) gene where the lissencephaly is more severe in anterior region of the brain. Usually this defect manifests in early infancy or childhood as seizure disorder. A case of lissencephaly with features of Miller Dieker syndrome in a young girl is reported and literature is reviewed. The important feature of the case was its late presentation in a 17 years old girl.
