Clinical question: Evaluate structural lesions to explain memory loss in a 50-year-old male. Signs and symptoms: Memory loss. Pre and post enhanced brain MRI:No acute intracranial process and negative diffusion weighted series.Examination demonstrate 2 punctate foci of nonspecific FLAIR hyperintensity in the right basal ganglia and a single linear focus of FLAIR hyperintensity in the splenium of corpus callosum. The findings are nonspecific, nonhemorrhagic and demonstrate no abnormal enhancement.The anatomical morphology and the signal intensity of brain parenchyma otherwise remains within normal on all MRI sequences for patient's stated age of 50.Unremarkable cerebral cortex, cortical sulci, ventricular system, CSF spaces and brain myelination otherwise.Signal voids of major intracranial arterial branches are identified and unremarkable.Signal intensity of intracranial venous sinuses are within normal.Post contrast images demonstrate no abnormal enhancement of brain parenchyma or the leptomeninges.Unremarkable images through the orbits and including axial fat sat post enhanced series.Normal enhancement of intracranial venous sinuses.Unremarkable calvarium and soft tissues of the scalp.All the paranasal sinuses and bilateral mastoid air cells and middle ear cavities demonstrate normal pneumatization signal pattern with the exception of minute bilateral maxillary mucosal thickening.
1.No acute intracranial process and negative diffusion weighted series.2.3 tiny foci of nonspecific FLAIR hyperintensity 2 in the right basal ganglia and one in the splenium of corpus callosum as detailed.3.Unremarkable pre and post enhanced brain MRI otherwise for patient's stated age of 50.
