Neuroimaging in neurocysticercosis. CT scans showing different phases of neurocysticercosis. Top left: CT scan showing many calcifications and active cysts with scolices in both hemispheres. Top right: T1-weighted MRI showing 2 active cysts with the scolex in their interior (vesicular phase). Bottom left: Postcontrast CT scan showing a ring-enhancing cyst (colloidal phase) on left. Bottom right: Proton density-weighted MRI showing a thick capsule with adjacent scolex and perilesional edema (colloidal phase).
Neuroimaging in neurocysticercosis. Natural history of neurocysticercosis. Top left: This CT scan shows a large occipital active cyst (vesicle phase), many calcifications, and small cortical cysts. Top right: After 18 months, the occipital cyst has been replaced by a calcification and the remaining cysts have disappeared. Bottom left: A single parietal nodular-enhancing lesion (transitional, nodular-granular phase) is shown. Bottom right: Six months later, the lesion has disappeared.
Neuroimaging in neurocysticercosis. Noncontrast and contrast-enhanced CT scan of neurocysticercosis. Left: Normal noncontrast CT scan. Right: After administration of the contrast medium, the CT scan of the same patient shows a single parietal nodular-enhancing lesion (transitional, nodular phase).
Neuroimaging in neurocysticercosis. Cysticercotic encephalitis. Left: Contrast-enhanced CT scan showing multiple, small, nodular, and annular areas of abnormal enhancement in brain parenchyma. Right: Gadolinium-enhanced T1-weighted MRI showing hyperintense lesions.
