Nervous system images Flashcards
What pathology is shown here?
Meningitis
What pathology is shown here?
Hydrocephalus
A: Massively dilated lateral ventricles-pushing the tissue together making it harder for good functioning
What pathology is shown here?
Hydrocephalus
-Stenosis (black arrow)
-Everything prior is dilated
-Fourth looks normal
What radiodensity is shown here?
VP shunt for hydrocephalus
What pathology is shown here?
Hydrocephalus
-Another example of enlargement
-Chiari malformation; brain stem pushing downwards
What pathology is shown here?
Brain tumour
A: Astrocytoma- Causing a midline shift
-mass effect-effect that it has on the brain
B: Astrocytoma-see darker tissue around
What pathology is shown here?
Glioblastoma with and without contrast
-Midline shift with mass effect
What pathology is shown here?
Meningioma
-When you add contrast they enhance very brightly
-Come off meningies
What pathology is shown here?
Metastatic Carcinoma
-Contrast is needed, seeing them spread throughout the brain
What pathology is shown here?
Metastatic Carcinoma
-Both done with contrast
-Some can be circle shaped, curvy, irregular
-Surrounding all of them is edema
Right: 2 larger ones (same type of cancer, just very differently enhanced
What pathology is seen here?
Linear fracture through the base of skull
What pathology is shown here?
Linear fracture
What pathology is seen here?
Depression fracture
-Pushing the bone inwards
-Increased radiopacity
-See large hematoma outside
-Can see some mass effect occurring
What pathology is shown here?
Linear fracture spread out into smaller ones
What pathology is shown here?
Depression fracture
-Showing up more radiopaque because the bone overlaps each other
What pathology is shown here?
Basal skull #
What pathology is shown here?
Epidural Hematoma
What pathology is shown here?
Subdural Hematoma-acute
What pathology is shown here?
Subdural Hematoma-Seeing more bilaterally. Been over 3 weeks
What pathology is shown here?
Subdural Hematoma
-Older bleed that has started to bleed again
-Seeing older and newer bleed in the brain
-Seeing more of midline shift
What pathology is shown here?
Subarachnoid Hematoma
Looks like a contrast scan but without contrast
What pathology is shown here?
Brain Contusions
What pathology is shown here?
Nasal bone fractures
What pathology is shown here?
Nasal bone fractures
-Displaced fracture
What pathology is shown here?
Blow out fractures of the orbit
What pathology is this showing?
Le Fort fractures type 1
What pathology is shown here?
Le Fort fractures type 2
What pathology is shown here?
Tripod fracture
What pathology is shown here?
Mandibular fracture
What pathology is shown here?
Contrecoup fracture
What pathology is shown here?
Contrecoup fracture
What pathology is seen here?
AVM
What pathology is seen here?
Stroke
A: Comparison of the CT scan almost immediately before ethe MRI scan-MRI shows the area that has been damaged by the stroke
B: CT scan compared to MRI-MRI showing huge area on the right that you cannot really appreciate on the CT scan
What patholgy is seen here?
Hemorrhagic stroke-blood leaking out
What scan is done here?
Final part of a stroke protocol-CT perfusion study
What pathology is seen here?
Alzhimers disease
What pathology is seen here?
Alzhimers disease
What pathology is seen here?
Disc Herniation
What pathology is seen here?
Spondylosis
What pathology
Neuromuscular scoliosis
What pathology is seen here?
Kyphosis
What pathology is seen here?
Lordosis
What are we seeing in a and b?
A-Seeing a large area where the blood has decreased-blood volume has decreased, mean transit time decreased (never reaching the max)
-Non contrast scan looks normal but part of the brain is dead
B-Mismatch-change in colour, looks bad, but the blood volume isn’t that bad, its just taking longer
