On T1-weighted and fat-suppressed cranial MRI, hyperintensity consistent with intramural hematoma was observed within cervical and temporal petrous segments of left ICA (Figures 1(a) and 1(b)). On cervical and cranial MRA, marked decrease in the calibration of C1, and C2 segments of the left ICA was remarkable (Figure 1(c)).
