Cysticercosis remain a global public health problem in both the developing and developed countries. CT scan and MRI have been useful in the study of the evolution of the cysticercus within the brain parenchyma. MRI is more useful than CT scan in detecting intraventricular and subarachnoidal cysts, as well as the accompanying signs of cyst degeneration and pericystic inflammatory reaction. However, CT scan is preferred for detection of parenchymal calcifications.
Once the oncosphere has passed into the parenchyma, it grows and evolves through vesicular, colloidal, nodular-granular, and calcified phases. The racemose form constitutes a hydropic change that leads to large or even giant vesicles usually devoid of a scolex. Carpio proposed an improved and widely accepted classification system based on the viability and location of the parasite in the host CNS. Active, when the parasite is alive. Transitional, if it is in the degenerative phase. Inactive, if evidence of its death is apparent. Because of the variable clinical course of the disease, treatment must be individualized for each patient. It constitutes antiepileptic and antihelmintic therapy.
