case_images: Subarachnoid hemorrhage after posterior communicans artery aneurysm rupture. (a) CT image showing the subarachnoid hemorrhage (left) and the 3D angiography showing the posterior communicans aneurysm (arrow), which ruptured and led to the hemorrhage (right). (b) Physiological perfusion CT and the physiologic graphic character of the patient. (c) Pathophysiological perfusion CT on the left hemisphere (green) and dysgraphia. (d) Graphical analysis of the right and left hemispheres showing a pathological MTT of 4.1 s (cut off: 3.9 s) on the left hemisphere in the PCT after dysgraphia occurred

case_images: We present the case of a 47-year-old female admitted to our department with a ruptured posterior communicans artery aneurysm [Figure 1a]. Because of the surfacing dysgraphia [Figure 1b and c], we performed a TCD which was physiological and a PCT which showed a perfusion deficit on the left hemisphere with an MTT of 4.1 s [Figure 1b-d].
