Within <1 to 38 months after the qualifying incident, MRI of the brain was performed using a 3-tesla scanner and high-resolution susceptibility-weighted magnetic resonance sequences for detection of hemosiderin depositions, which were quantified by a score. [, Strandberg M, Larsson EM, Backman S, et al. Malformations related to abnormal stem cell development include the focal or transmantle cortical dysplasias (balloon cell or type II FCDs) and the hemimegalencephalies. Unauthorized use of these marks is strictly prohibited. However, in clinical practice, their diagnostic value, associated risk, and prognostic significance are often unclear. In order to understand the different types of malformations of cortical development it is important to briefly review the embryology of normal brain development: During the seventh week of gestation, neuronal proliferation in the subependymal germinal matrix occurs. What causes hemosiderin staining? The corresponding area has decreased signal on T1-weighted image. on the prevalence of epileptogenic lesions among 2740 patients the following pathologies were found: mesial temporal lobe sclerosis (32%), tumors (including low and high grade tumors as well as malformative tumors and benign epilepsy associated tumors) in approximately 17% of patients, cortical dysplasias in 11%, glial scars (including posttraumatic, post-ischemic, post-hemorrhagic, postinfectious/abscess, ulegyria, and postsurgical scars) in 11%, vascular diseases (cavernoma AVM, pial angiomatosis) in 5%, malformations of cortical development including nodular heterotopia, subcortical band heterotopia, polymicrogyria, lissencephaly, pachygyria, agenesis of corpus callosum, craniocephalic malformations, hemiatrophy, lobar dysgenesis, hemimegalencephaly, or hamartomas in 3%, and sequelae of encephalitis in 1% while in approximately 20% no lesion could be detected.
