This 24 year old female presented with seizuresAn MRI with gadolinium enhancement suggested a diagnosis of cysticercosis.Image (a) is a pre gadolinium T1 weighted coronal image showing a hypointense focus in the paramedian part of the frontal lobe.

Image (b) shows rim enhancement of the lesion.

Image (c) is a coronal T2 weighted image that shows a hyperintense centre with a dark rim. A hypointense scolex can be seen as a tiny linear defect within the cavity. Surrounding edema is present in the white matter.

Image(d) is a FLAIR coronal sequence and shows a dark matrix and edema in the surrounding white matter. The linear scolex inside the cavity is seen as relatively hyperintense.

These finding are consistent with the diagnosis of cysticercosis.
