    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.
