Flashcards in Congenital Malformation Deck (16):
1

Diastematomyelia

Spinal cord split in 2

2

Spina Bifida Cystica
(what is other one?)

herniation of spinal cord/meninges through vertebral arch defect
Spina bifida occulta

3

Spina bifida

Neural tube defect
failure posterior neuropore to close

4

Spina bifida Cystica with meningomyelocle

herniation of meninges, CSF and spinal cord

5

Spina bifida cystica - myeloschisis

spinal cord is open (neural folds didn't close)

6

Spina bifida cystica with meningocele

meninges and CSF herniated

7

Anencephaly

failure anterior neurpore to close
skull doesn't form, brain tissue degenerates (can't live)

8

Encephalocoele

failure anterior neuropore to close
herniation cerebrum through skull defect

9

Hydrocephalus

accumulation of CSF

10

Craniorachischisis

failure of entire neural tube to close

11

Polymicrogyria

excessive small gyri

12

Lissencephaly

smooth brain due to defect of neuronal migration

13

agenesis corpus callosum

failure of corpus callosum to develop

14

Porencephaly

CSF filled cysts

15

Microcephaly

small underdeveloped brain

16

Schizencephaly

clefts in cerebrum
