Neuropathology Flashcards
What does this show
Cytoplasmic neuronal vacuolation in spongiform encephalopathies
Round clear space within cytoplasm of neurons
e.g. scrapie
What are routes of entry into the brain
Haemotogenous (streptococci)
Intraaxonal (rabies)
Direct extension (from sinusitis, otitis, abcesses etc.)
Within leucocytes (canine distemper virus)
Types of degenerative diseases
Metabolic-toxic diseases (e.g. grass sickness in horses)
Nutritional diseases (selenium poisoning in pigs)
Hereditary diseases (storage diseases)
What is cerebral cortical necrosis
Necrosis of grey matter
Clear spaces start to appear in deep cortex
Caused by thyamine deficiency
What does this show
Swollen neurons due to (lysosomal) storage disease
