Learning objectives

• To recognize the imaging findings of parenchymal and extraparenchymal neurocysticercosis. • To demonstrate the main intracranial complications of cysticercosis.

Background

Neurocysticercosis (NC) is the larval phase ofTaenia soliumin the human central nervous system (CNS). Fig. 3 It is the most common CNS parasitic infection, and also one of the most common causes of seizures in endemic areas. Much information has been generated in different parts of the world but, there is still uncertainty regarding NC prevalence and incidence.

Findings and procedure details

According to the location of the parasite, NC can be divided into parenchymal and extraparenchymal forms which present with different clinical and imaging findings.Fig. 4Parenchymal NC has four well defined anatomopathological stages — vesicular, colloidal, granular nodular, and calcified — which have a good correlation to imaging findings. It is worth noting that lesions of different stages can be found in the same patient. In the vesicular stage, a cyst can be characterized next to the gray-white junction with a thin margin with a little...

Conclusion

Familiarity with the imaging findings may help in early diagnosis, appropriate treatment decisions, and follow-up of patients with neurocysticercosis.
