Signs and symptoms: Intermittent visual field blurriness of few seconds duration. Pre and post enhanced brain MRI:There is normal anatomical morphology of brain parenchyma and with normal signal intensity on all MRI sequences.Unremarkable cerebral cortex, cortical sulci, ventricles and brain myelination.There is no detectable abnormal parenchymal or leptomeningeal enhancement. Images through the orbits and including axial fat sat post enhanced series are unremarkable.Calvarium and skull base are unremarkable.Visualized paranasal sinuses demonstrate small air- fluid level in the sphenoid sinus and unremarkable otherwise.
