Overview

Cysticercosis must be differentiated from other diseases that cause brain lesions and ocular lesions.

Disease Prominent clinical feature Lab findings Radiological findings
Neurocysticercosis
  • Parenchymal lesions: Presentation depends on the site and number of lesions.

Seizures are the most common presentation. It is mostly focal but can have a secondary generalization.

Lab findings are nonspecific.
Brain abscess
  • Headaches are the most common symptom. Usually, headaches occur on the same side of the abscess and tend to be severe (not responding to analgesics).
  • Fever is not a reliable sign .(2)
  • Lumbar puncture is contraindicated but when done, it was variable between patients.
  • Culture from the CT-guided aspirated lesion helps in identifying the causative agent.
Contrast enhances CT provides rapid assessment of the size and number of the abscesses.

MRI : Diffusion weighted imaging (DWI) MRI can differntiate brain abscess from cystic brain lesions with sensitivity and specifity of 96% (3)

Brain tumors
Brain tuberculoma
Neurosarcoidosis
Encephalitis
