1. Fig 13. 26 year- old normotensive man with intact coagulation who presented to emergency room with decreased level of consciousness. Axial non- contrast CT scans show an acute left parietotemporal IPH with asociatted IVH and SAH. A MDCTA was rejected.

2. Fig 14. Same patient that figure 13.Axial DP ( a) and T2EG (b and c)weighted MR images show dilated striate-thalamic arteries arrow) and artefacts secondary hemosiderin deposits from old hematoma.

3. Fig 15. Same patient that figure s 13 and 14.MIP images obtained from RM angiography( on the left) and DSA image ( on the right) show main intracranial vessels decreased of caliber with stenosis and colateral circulation consistent with Moya-Moya disease.

4. Fig.16. 65 –year –old man who went to other hospital emergency room with headache, and visual disturbances. A non-contrast axial CT scan was realized.He was diagnosed of intracranial hematoma.Surgical evacuation was performed.A posterior non contrast CT was realized.Axial non –contrast CT images show similar findings with and extraaxial collection and multiples hypodense areas consistent with infartcs.

5. Fig 17. Same patient that figure s 16.Axial DP, Flair,T2,T1 and sagittal T1weighted MR Images showed an abnormal collection of vessels in the left occipital lobe consistent with arteriovenous malformation.

6. Fig18. Right parietal subcortical hematoma in a 82 year-old man who went to emergency room with seizures.Axial T1 weighted image show a well defined lesion with hyperintese areas consistent. Hematoma secondary to amiloid cerebral angiopathy was confirmed after it was drained.

7. Fig19. Infarct with hemorrhagic trasnformation in a young man. Axial CT scans also show an hyperdense rectum sinus. Axial with contrast T1 weighted MR images shows thrombosis of the left transverse and sigmoid sinus extending into the left yugular vein.

8. Fig20. Same patien that figure 19. MIP images obtained from a RM angiography show thrombosis of the left transverse and sigmoid sinuses extending into the left yugular vein.Volume-rendered image (in first plane) shows similar findings.
