Figure 4: Arteriovenous malformation. Acute focal neurologic symptoms. Stroke code: 45 years old male presenting with right hemiparesis, weakness, impairment of speech and alteration of consciousness (NIHSS 6). a) No-contrast brain CT and b) CTA findings were negative. d) T2- weighted MRI shows ectasic surface vessels in the left frontal lobe, better appreciated on (e) SWI. f) Quantitative ASL (OLEA sphere 3.0): focal hypoperfusion corresponding to the left Rolandic cortical area adjacent to ectasic cortical vessels. 3D-TOF MRA(g,h) (single slice and MIP) shows the abnormal dilated vessels embedded left frontal lobe and (f) the DSA on lateral left carotid angiograms demonstrate the left frontal AVM with a nidus supplied by an enlarged branch of MCA. Note the early drainage to a frontal cortical vein into the superior sagittal sinus (and via an internal cerebral vein to the straight sinus). Diagnosis: frontal AVM inducing focal hypoperfusion of left Rolandic cortical area caused the acute neurologic symptoms.
