Focal cortical dysplasia type III Focal cortical dysplasia type IIIc 2018-09-16T11:23:39Z true true https://www.ncbi.nlm.nih.gov/pubmed/31085954 A subtype of focal cortical dysplasia type III that is characterized by alterations in architectural (cortical dyslamination, hypoplasia) or cytoarchitectural composition of the neocortex (hypertrophic neurons), which occur adjacent to vascular malformations (cavernomas, arteriovenous malformations, leptomeningeal vascular malformations, telangiectasias, meningioangiomatosis). FCD Type III describes FCD that occurs in combination with hippocampal sclerosis (FCD Type IIIa), with glioneuronal tumors (FCD Type IIIb), adjacent to vascular malformations (FCD Type IIIc) or in association with lesions acquired in early life, such as a previous ischemic injury (FCD Type IIId). http://www.case.edu/EpSO.owl#FocalCorticalDysplasiaTypeIIIC peter FCD Type IIIC (Cortical Lamination Adjacent to Vascular Malformation)
