78 Possible Causes for Cisterna Magna Enlarged

  • Mega-Cisterna Magna

    In general isolated mild cisterna magna enlargement ( between 10 to 13 mms ) is associated with good prognosis in the child after birth .[] ENLARGED / MEGA-CISTERNA MAGNA BLAKE’S POUCH CYST Cisterna magna enlarged - 10mm. Free communication with perimedullary subarachnoid space.[] An enlarged cisterna magna usually measures 10 mm on midsagittal images. An enlarged posterior fossa can sometimes be present 6 .[]

  • Patau Syndrome

    . * Agenesis of the Corpus Callosum * Enlarged Cisterna Magna. * Microcephaly. * Meningocele / encephalocele.[] cisterna magna agenesis of the corpus callosum persistent stapedial artery 5 retinal dysplasia 3 spinal anomalies spina bifida intrauterine growth restriction (IUGR) : tends[] Agenesia (complete) absence of the corpus callosum enlarged cisterna magna Eye malformations: Coloboma : Gap formation of the iris, lense or choroid Retinaal abnormalities[]

  • Dandy-Walker Syndrome

    On an axial tomogram, an enlarged cisterna magna could not be distinguished from a Dandy-Walker variant, nor could an encysted fourth ventricle be distinguished from a subarachnoid[] This is caused by open communication of the posteroinferior fourth ventricle and the cisterna magna through the enlarged vallecula.[] Mega cisterna magna Mega cisterna magna (see the image below) consists of an enlarged posterior fossa secondary to an enlarged cisterna magna, with a normal cerebellar vermis[]

  • Neurogenic Arthrogryposis Multiplex Congenita

  • Communicating Hydrocephalus

    cisterna magna.[] […] ventricles, a downward bulging floor of the 3rd ventricle (interpreted as a sign of pressure gradient between the ventricles and basal cisterns) and a free communication to an enlarged[]

  • Mucopolysaccharidosis

    A brain MRI revealed enlarged cisterna magna along with cerebellar tonsils ectopia consistent with CM-I.[] magna was the most common radiologic finding.[] Spinal MRIs usually revealed canal stenosis and cord compression with spinal cord signal changes [ Table 2 ].[ 26 ] Looking specifically at the posterior fossa, mega cisterna[]

  • Cerebral Cortical Atrophy

    There was no other atrophy of infratentorial structures except for occasional enlargement of the cisterna magna and cerebellopontine angle cisterns.[] Vermian atrophy did not correlate with cerebral atrophy (enlargement of either lateral ventricles or cortical sulci).[]

  • Central Nervous System Cyst

    Enlarged cisterna magna is diagnosed if the vertical distance from the vermis to the inner border of the skull is more than 10 mm.[] (partial agenesis of the cerebellar vermis without enlargement of the posterior fossa), and (c) mega-cisterna magna (normal vermis and fourth ventricle).[] Experience with apparently isolated partial agenesis of the vermis or enlarged cisterna magna is limited and the prognosis for these conditions is uncertain.[]

  • Gingival Fibromatosis-Progressive Deafness Syndrome

    cisterna magna Long foot Neuroblastoma Apraxia Otitis media Genu valgum Renal agenesis Congenital hypertrophy of retinal pigment epithelium Delayed speech and language development[] […] septum pellucidum Partial agenesis of the corpus callosum Overbite Teratoma Advanced eruption of teeth Periventricular leukomalacia Poor coordination High anterior hairline Enlarged[]

  • Rieger Syndrome

    Two patients had an enlarged cisterna magna, one with a malformed cerebellum, and two had executive skills deficits one in isolation and one in association with a below average[]
