A well-defined cystic space-occupying lesion is seen in the left inferior part of the temporal region against the greater wing of the sphenoid bone, measures 33 x 30 mm. It follows CSF density with a smooth surface, no perifocal brain edema and exerts no mass effect, the findings in favor of an arachnoid cyst.
