(a) Noncontrast head CT: bilateral hematomas are present. These are predominantly isodense to slightly hypodense compared to the adjacent gray matter (29-35 Hounsfield units), which could be explained by anemia (hemoglobin was 9 g/dL). (b) and (c) Bilateral subdural hematomas, confirmed as shown in both MRI T2 and FLAIR sequences.

CT scan revealed a bilateral high density subdural haematoma at the brain convexity without significant mass effect, SAH, or ICH (intracerebral hemorrhage); MRI confirmed the CT diagnosis (Figure 1).
Left internal carotid DSA: AP (a) and lateral views, (b) demonstrating aneurysm of left PCoA, (c) AP view after embolisation (coils) showing complete obliteration of the aneurysm.

This revealed a left saccular PCoA aneurysm (4.5 * 7.5 mm) (Figures 2(a) and 2(b)). AP-view angiography showed an irregular shape of the aneurysm with additional small outpouching indicating possible point of rupture at the inflow zone (Figures 2(a) and 2(b)). The patient underwent successful coiling of the aneurysm (Figure 2(c)).
