CNS path

CNS pathology

epidural hematoma arterial hemorrhage associated with skull fracture and most often laceration of branches fo the middle cerebral artery
epidural hematoma characterized clinically by a short period of consciousness followed by rapidly developing signs of cerebral compression
intracranial hemorrhage most frequently caused by HTN, most occur in basal ganglia/thalmus
subarachnoid hemorrhage associated with berry aneurysm of the circle of Willis; also caused by A-V malformations, trauma, or hemorrhagic diathasis
cerebral infarction characterized by liquefactive necrosis leading to cyst formation, cuased by arterial occlusion from thrombi or emboli
are the most frequent sites of thrombotic occlusion carotid bifurcation and middle cerebral artery
middle cerebral artery most frequent site of embolic occlusion
arnold chiari malformation downward displacement of cerebellar tonsils and medulla through foramen magnum
arnold chiari malformation results in pressure atrophy of displaced brain tissue, causes hydrocephalus by obstruction of CSF outflow tract
hydrocephalus increases volume CSF withing cranial cavity, most often caused by obstruction to CSF circulation, can also result from overproduction of CSF by choroid plexus papilloma
hydrocephalus ex vacuo caused decreased cerebral mass
meningocele herniated membranes consisting of meninges only
meningomyelocele portion of spinal cord included in herniated tissue
anencephaly marked diminution of fetal brain tissue, usually associated with absence of overlying skull
subdural hematoma caused by venous bleeding, most often from bridging veins, joining the cerebum to venous sinuses within the dura
subdural hematoma characterized by gradual signs of cerebral compression occuring hours to days to weeks after injury
spina bifida occulta spina bifida with no clinically apparent abnormalities; vertebral arch defect most often limited to one or two vertebrae
spina bifida failure of posterior vertebral arches to close
spina bifida cystica spina bifida complicated by herniation of meninges through a defect
