Clinical question: Subacute loss of memory. Signs and symptoms: Subacute loss of memory. Pre and postcontrast enhanced brain MRI:Negative diffusion weighted series.Examination demonstrates mild generalized prominence of cortical sulci which could be within the normal range for age. There is no significant change of this finding when compared with prior exam from 2003.Unremarkable anatomical morphology and signal intensity of brain parenchyma otherwise on all MRI sequences. Unremarkable cerebral cortex, ventricular system, CSF spaces and gray-white matter differentiation.The signal voids of major intracranial arterial branches are identified.Post enhanced images demonstrate no abnormal enhancement of brain parenchyma, leptomeninges, calvarium, soft tissues of the scalp or the orbits.The signal intensity of the intracranial venous sinuses are within normal and with normal pattern of enhancement.
Unremarkable pre and post enhanced brain MRI. Please see above comments.
