Study Notes
Hydrocephalus and CSF
- Abnormalities in CSF reabsorption or production can lead to hydrocephalus.
Visual Field Assessment
- Visual field assessment can be done via a bedside confrontational test.
Subdural Hemorrhage
- Subdural hemorrhage usually results from tearing of bridging veins.
Traumatic Brain Injury (TBI)
- Prolonged antiepileptic treatment may be necessary in some TBI cases.
Horner's Syndrome
- Horner's syndrome is characterized by miosis (pupil constriction), ptosis (drooping eyelid), and facial anhidrosis.
- Mydriasis (dilated pupil) and exophthalmos (protruding eyeball) are not associated with Horner's syndrome.
Brain Tumors
- Meningiomas are not the most common primary brain tumors in children.
Lumbar Puncture
- Lumbar puncture is contraindicated in cases with space-occupying brain lesions due to the risk of herniation.
Ischemic Stroke
- Ischemic stroke is primarily diagnosed with MRI scans.
Internal Capsule Lesions
- Lesions in the internal capsule do not usually result in visual deficits.
Vasogenic Edema
- Dexamethasone and mannitol are used for the treatment of vasogenic edema.
Oculomotor Nerve Palsy
- Oculomotor nerve palsy can be caused by posterior communicating artery aneurysm.
Metastasis Screening
- MRI of the spine is often done for metastasis screening in patients with medulloblastoma.
Intracranial Hemorrhage (ICH)
- Intracranial hemorrhage (ICH) is not commonly located in the frontal lobe.
CSF Production
- CSF is not produced predominantly by the arachnoid villi.
Brain Death Diagnosis
- Diagnosis of brain death cannot be made only with clinical examination.

Description
Test your knowledge about the cerebrospinal fluid (CSF) and the visual pathway with this quiz. Learn about the normal volume of CSF in adults, abnormalities in CSF reabsorption or production, its role as a cushion to protect the brain, and visual pathway-related conditions such as optic nerve lesions and pituitary macroadenoma.
