 This is a limited MRI of the brain for preoperative planning. There is suggestion of mild asymmetric volume loss of the right hippocampal head. The previously seen signal abnormality is not well appreciated compared to the prior study due to limited sequences and planes. There is suggestion of left cerebellar volume loss.The ventricles and sulci are otherwise unchanged. There is a cavum septum pellucidum and vergae with convex borders and slight leftward bowing of the internal cerebral veins, favoring a cyst. The cisterns remain patent. There is no midline shift or mass effect. There are no areas of abnormal signal or pathological enhancement. There is a thin area of hypoenhancement with T2 hypointense signal in between the anterior and posterior pituitary gland, possibly representing a pars intermedia cyst. No extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits.
