9 Possible Causes for Agenesis of the Occipital Lobes

  • Congenital Muscular Dystrophy

    Uncommonly, agenesis of septum pellucidum can be seen. Polymicrogyria typically seen in the frontal and parietal lobes.[neuroradiologycases.com] Pachygyria in approximately half of patients, typically involving the temporal and occipital lobes. Cerebellar polymicrogyria is seen in approximately 90% of patients.[neuroradiologycases.com]

  • Crossed Polysyndactyly

    Computerized to- mography showed severe craniofacial anomalies, cranio- nasal dysostosis, hypertelorism, areas of pachygyria in the left occipital lobe, and agenesis of the[documentslide.com]

  • Occipital Encephalocele

    MRI also showed mild hydrocephalus, hypoplasia of the corpus callosum and tentorium cerebelli, dropping down of the bilateral occipital lobes and vermicular agenesis.[link.springer.com] Magnetic resonance imaging (MRI) clearly showed an occipital cephalocele with a tiny cystic component connecting to the subarachnoid space.[link.springer.com]

Frontal brain is fused, thalami partially fused.[spinwarp.ucsd.edu] The frontal horns are hypoplastic with absent septum pellucidum, (c) Sagittal T2-weighted image shows agenesis of body of corpus callosum (arrows) with normal splenium and[pediatricneurosciences.com]

  • Pachygyria-Mental Retardation-Seizures

    Semi lobar: Partial separation of the posterior occipital and temporal lobes. Frontal brain is fused, thalami partially fused.[spinwarp.ucsd.edu] CT showed findings consistent with agenesis of the left parietal and partly also temporal lobe.[documents.tips] Corpus callosum agenesis. Dandy Walker. Facial anomalies. Holoprosencephalies Failure to separate into hemispheres.[spinwarp.ucsd.edu]
