Figure 7

A 47-year-old male with sudden onset of severe headache. TOF-MRA and DSA demonstrated. The SWI (a) sequence illustrated right paraventricular hemorrhage. The fusion of the TOF-MRA and SWI sequences (c) showed that the choroidal artery was the most possible responsible vessel. TOF-MRA (b) demonstrated an aneurysmal structure (b). Cerebral microbleeds (CMBs) were also spotted in the SWI sequence ((d, e) white arrow).
