‼️Patho-CNS Flashcards
Sequelae of brain volume expansion
Herniation
Formula for CPP
CPP = MAP - ICP
Unilateral or assymetric expansion of the cerebral hemisphere displaces the cingulate gyrus under the falx cerebri
Subfalcine (cingulate) herniation
Subfalcine herniation may lead to the compression of which artery
ACA
Medial temporal lobe compressed against the free margin of the tentorium
Transtentorial herniation
In transtentorial herniation, contralateral peduncle compression causing ipsilateral hemiparesis to the side of the herniating part is called
Kernohan’s notch
Hemorrhagic lesions in the midbrain and pons on transtentorial herniation is called
Duret hemorrhages
Life threatening herniation
Tonsillar herniation
Flattened remnant of disorganized brain tissue in anencephaly is called
Area cerebrovasculosa
Failure of closure of the anterior neuropore
Anencephaly
Failure of closure of the posterior neuropore
Spina bifida
What is Hydrocephalus ex vacuo?
Dilation of the ventricular system with a compensatory inc in CSF volume
