Fig. 1

Computed tomography (CT) image of the current patient showing Sylvian fissures, which were not clearly visible bilaterally (a), compared to a CT image of the same patient taken 2 years ago when the patient complained of occipital headache, nausea, and vomiting. At that time, no abnormalities were detected (b). There was mainly isoattenuating SAH in the Sylvian fissures (slightly hyperattenuating on the left) and mild hydrocephalus - seen as enlargement of the third ventricle (a) in comparison to the previous CT (b). An arrow indicates Sylvian fissure, and an arrowhead indicates the dilated third ventricle
