Overview
Differentiating [Disease name] from other Diseases
Pseudotumor cerebri must be differentiated from other diseases that cause increased intracranial pressure:
Secondary intracranial hypertension
- Obstruction of venous outflow, eg, venous sinus thrombosis, jugular vein compression, neck surgery
- Decreased CSF absorption, eg, arachnoid granulation adhesions after bacterial or other infectious
- meningitis, subarachnoid hemorrhage
- Increased cerebrospinal fluid (CSF) production, eg, choroid plexus papilloma
- Malignant systemic hypertension
Most of these condition can be ruled out by imaging techniques like MRI, CT scan and MR venography.[1][2]
Bilateral disc abnormalities
- Pseudopapilledema: Some non-diseased conditions like congenital disc abnormalities ( drusen and myelinated nerve fibers), farsightedness and hyperopia can cause the appearance of papilledema[3][4]
- Malignant hypertention: Severe systemic hypertension can mimic papilledema but it also cause other signs like hemorrhages, exudates, cotton wool spots, diplopia, scotomata and photopsia which help us differentiate it from other causes of papilledema.[5][6]
- Diabetic papillopathy: Diabetic papillopathy can mimic papilledema from increased intracranial pressure with telangiectasias, hemorrhages and macular star.[7]
- Hyperviscosity, hypotension, and blood loss[8]
- Toxic optic neuropathies: methanol, ethambutol and ethylene glycol can cause papilledema early in their course.[9]
