Brain computed tomography (CTA) and digital subtraction angiography (DSA) were performed to evaluate for vascular abnormalities, and these angiographic studies revealed a 5 x 3 mm sized aneurysm at the A3-A4 junction of left ACA (Fig. 1).

SAH was not observed at the aneurysm site, with only the rupture point detectable at the site of the aneurysm (Fig. 2).
a, b Postoperative CTA revealed that previous subdural hematoma was evacuated and aneurysm was clipped without a remnant sac (arrow)
