case_images: The brain magnetic resonance imaging (MRI) showed a fourth ventricle cyst, 2.6 x 1.8 cm (cephalocaudal x transverse axis) with an enhancing nodule compatible with a scolex and associated obstructive hydrocephalus [Figures 1 and 2].
case_images: Preoperative axial T2-weighted fast field echo showing the hypointense four cup-shaped suckers of the scolex.
