Study Notes
Hydrocephalus
- Non-communicating hydrocephalus is most commonly caused by obstruction within the ventricular system.
- Communicating hydrocephalus affects the whole ventricular system.
Cranial Abnormalities
- Craniosynostosis, a degenerative disease, is associated with enlargement of the head due to cranial sutures closure in hydrocephalus.
Neurodegenerative Disease
- Amyloid Aß surrounded by tortuous silver-stained neurites characterizes Alzheimer's disease.
Increased CSF Production
- Choroid plexus papilloma, a rare scenario, causes increased CSF production leading to hydrocephalus.
Necrosis and Ischemia
- Coagulative necrosis is associated with cerebral infarction.
Intracerebral Hemorrhage
- Hypertension is the leading cause of intracerebral hemorrhage.
- The basal ganglia are the most common site for intracerebral hemorrhage.
Meningitis
- In acute septic meningitis, Streptococcus pneumoniae is the most common causative agent.
- In acute aseptic meningitis, lymphocytes are the predominant inflammatory cells.
