case_images: Brain computed tomography (CT) of the patient. CT obtained 2 days after the onset of the first headache showing bilateral subdural effusions (arrows) and slit-like lateral ventricles with an arachnoid cyst in the right temporal fossa (a). CT obtained at recurrence of headache showing a hyperdense right subdural hematoma and a hyperdense change in the arachnoid cyst with obvious compression of the right lateral ventricle and evident midline shift to the left (b). CT obtained 3 months after surgery showing no change in the volume of the arachnoid cyst and no recurrence of subdural hematoma with the lateral ventricles and subdural space normal in size (c).

case_images: Computed tomography (CT) revealed bilateral subdural effusions and slit-like lateral ventricles with no significant changes to the AC [Figure 1a]. The neurological examination was still unremarkable but repeat CT after another month revealed a hyperdense right subdural hematoma (SDH) and a hyperdense change in the AC with obvious compression of the right lateral ventricle and evident midline shift to the left [Figure 1b]. The lateral ventricles and subdural space were again normal in size [Figure 1c].
