MRI of the brain, using Turbo Spin Echo, Fluid Attenuated Inversion Recovery, and Gradient Echo sequences, was conducted before and after intravenous administration of contrast medium. Results showed the presence of a roundish area of approximately 1.5 cm in diameter located in the vicinity of the quadrigeminal cistern at the level of the pineal gland. There was also a slight dilation of the supratentorial ventricular system, which appeared in the axis and was most evident in the proximity of the temporal horns, with a periventricular rim with a transependymal fluid absorption phenomenon.<ref>Peter H Yang, Alison Almgren-Bell, Hongjie Gu, Anna V Dowling, Sangami Pugazenthi, Kimberly Mackey, Esther B Dupépé, Jennifer M Strahle.
