Overview

Differential Diagnosis

Neuroyphilis has an extensive differential diagnosis.

Diseases Diagnostic tests Physical Examination Symptoms Past medical history Other Findings
Na+, K+, Ca2+ CT /MRI CSF Findings Gold standard test Neck stiffness Motor or Sensory deficit Papilledema Bulging fontanelle Cranial nerves Headache Fever Altered mental status
Neurosyphilis[1][2] ✔ ↑ Leukocytes and protein
  • CSF FTA-Ab -sensitive[3]
 ✔ ✔ ✔ ✔ ✔ ✔
  • Unprotected sexual intercourse, STIs
  • History of multiple sexual partners.
Brain tumour[4][5] ✔ Cancer cells[6] MRI ✔ ✔ ✔ ✔ ✔ ✔ Cachexia, gradual progression of symptoms
Wernicke’s encephalopathy Normal ✔ ✔ ✔ History of alcohal abuse Ophthalmoplegia, confusion
CNS abscess ✔ ↑ leukocytes >100,000/ul, ↓ glucose and ↑ protien, ↑ red blood cells, lactic acid >500mg Contrast enhanced MRI is more sensitive and specific,

Histopathological examination of brain tissue

✔ ✔ ✔ ✔ ✔ ✔ ✔ History of drug abuse, endocarditis, ↓ immune status High grade fever, fatigue,nausea, vomiting
Electrolyte disturbance ↓ or ↑ Depends on the cause ✔ ✔ Confusion, seizures
Subdural empyema ✔ Clinical assesment and MRI ✔ ✔ ✔ ✔ ✔ ✔ History of relapses and remissions Blurry vision, urinary incontinence, fatigue
Delirium tremens ✔ Clinical diagnosis ✔ ✔ ✔ ✔ ✔ ✔ Alcohol intake, sudden witdrawl or reduction in consumption Tachycardia, diaphoresis, hypertension, tremors, mydriasis, positional nystagmus,
Subarachnoid hemorrhage[7] ✔ Xanthochromia[8] CT scan without contrast[9][10] ✔ ✔ ✔ ✔ ✔ ✔ ✔ ✔ Trauma/fall Confusion, dizziness, nausea, vomiting
Stroke ✔ Normal CT scan without contrast ✔ ✔ ✔ ✔ ✔ TIAs, hypertension, diabetes mellitus Speech difficulty, gait abnormality
Viral encephalitis ✔ Increased RBCS or xanthochromia, mononuclear lymphocytosis, high protein content, normal glucose Clinical assesment ✔ ✔ ✔ ✔ ✔ ✔ ✔ Tick bite/mosquito bite/ viral prodome for several days Extreme lethargy, rash hepatosplenomegaly, lymphadenopathy, behavioural changes
Herpes simplex encephalitis ✔ Clinical assesment ✔ ✔ ✔ ✔ ✔ History of hypertension Delirium, cortical blindness, cerebral edema, seizure
Drug toxicity ✔ ✔ Lithium, Sedatives, phenytoin, carbamazepine
Conversion disorder Diagnosis of exclusion ✔ ✔ ✔ ✔ ✔ Tremors, blindness, difficulty swallowing
Febrile convulsion Not performed in first simple febrile seizures Clinical diagnosis and EEG ✔ ✔ ✔ ✔ Family history of febrile seizures, viral illness or gastroenteritis Age > 1 month,
Hypoglycemia ↓ or ↑ Serum blood glucose

HbA1c

✔ ✔ ✔ History of diabetes Palpitations, sweating, dizziness, low serum, glucose
