Papilledema is optic disc swelling due to axoplasmic stasis caused by raised intracranial pressure. It is typically associated with symptoms of elevated intracranial pressure, such as headaches, pulsatile tinnitus, and transient visual obscurations. The visual hallmarks are relatively spared visual acuity in the setting of bilateral optic disc edema with enlarged blind spots, nasal visual field loss, or constriction of the visual fields.

The most common CNS infection caused by Listeria monocytogenes is meningitis, though rhombencephalitis, encephalitis, cerebritis, and abscess also occur. Neonates, the elderly, pregnant women, and immunocompromised patients are at highest risk of developing listerial meningitis, though a notable minority of patients is without risk factors. Clinical manifestations of CNS listeriosis depend on the involved neuroanatomy but commonly include fever, headache, altered sensorium, nuchal rigidity, hemiplegia, cranial nerve palsies, and seizure.
