Posterior Quadrantic Dysplasia: An Uncommon Cause of Childhood Seizures with Brief Review of Literature

Abstract

ABSTRACT Posterior quadrantic dysplasia (PQD) is a rare cause of medically refractory seizures among the paediatric population. We are reporting a case study of a 14-year-old female child with refractory seizures with seizure onset since birth. She was diagnosed with Posterior quadrantic dysplasia in left temporo-occipito-parietal lobes on magnetic resonance imaging. Our case report highlights the diffusion tensor imaging (DTI) and tractography along with routine magnetic resonance imaging findings in a classical presentation of PQD. DTI helps in proper delineation of white matter tract abnormalities and consequently in the approach for the surgical management. It is vital for radiologists to be familiar with these imaging findings for early diagnosis and treatment of PQD.
