DSA images displayed the left ICA angioarchitecture from various examinations. Two micro AVMs, which were identified in the last examination (B- a–c), were not diagnosed in the first three DSA examinations (A- a–c). Arrows pointed at the feeding arteries of AVMs before embolization (B- a, b); and arrowheads showed the embolised feeding arteries after embolization (B- c)
