Cerebrospinal Fluid and Visual Pathway Quiz

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.
