Figure 3: Axial and reformatted sagittal 3D-FIESTA images (a and b) demonstrate a cyst with scolex in the left frontal horn (arrow in a) and that the large cystic lesion is located inside the ventricle, associated to another scolex (arrowhead in b). A color map (c) proportional to relative cerebral blood volume (rCBV) obtained from a dynamic susceptibility contrast perfusion (T2*) study shows the lesion has no increase in rCBV. Single-voxel MR spectroscopy placed in the center of the cyst (d) demonstrates peculiar metabolites found in parasitic cysts, such as lactate, alanine and succinate
