Intro And Cranial Trauma Flashcards
This is suited for frontal sinus
Caldwell view
What is the other name of waters view
Occipitomental view
What is your first diagnostic procedure when it comes to head trauma
Conventional radiography
This is performed in unconscious patients with sever head injury
Cranial CT scan
This is used in the detection of acute epidural and subdural hematoma and non hemorrhagic brain injury
MRI
3 types of fracture
Linear
Depressed
Diastatic
This type of fracture is commonly seen among infants or children
Diastatic
What are the physical signs of temporal fracture
Hemotympanum
CSF otorrhea
Battle sign
What are findings of head CT scan in temporal fracture
Opacification of the mastoid air cells
Fluid in the middle ear
Pneumocephalus
Pneumolabyrinth
What are the types of temporal fracture
Longitudinal
Transverse
This fracture line is along the axis of the petrous bone
Longitudinal temporal bone fracture
This fracture may involve the carotid canal or jugular foremen causing injury to the carotid artery or jugular vein
Transverse temporal bone fracture
This type of head injury occurs as a first result of a blow to the head
Primary lesions
What are the type of extra axial primary lesions
Epidural hematoma
Subdural hematoma
Subarachnoid hemorrhage
Intraventricular hemorrhage
What are the types of intraaxial primary lesions
Diffuse axonal injury
Cortical contusions
Intracerebral hematomas
Subcortical gray matter injury
what are the types of secondary lesions
Cerebral swelling Brain herniation Hydrocephalus Ischemia Csf leak Leptomeningeal cyst Encephalomalacia
Epidural hematoma in CT scan is describe as
Lenticular
Biconvex
This type of hematoma is arterial in origin
Epidural hematoma
This is crescentric
Extra axial collection
Does not cross the falx cerebri and tentorium
Can cross sutural margins
Subdural hematoma
Linear areas of high attenuation within the cisterns and sulci
Subarachnoid hemorrhage
Small petechial hemorrhage at the gray white matter junction or corpus callosum
Diffuse axonal injury
Which area of the focal brain is cortical contusion seen
Superficial gray matter
Cortical contusion occurs where
Bony protuberance
