Figure 1

(a) Axial nonenhanced CT scan on admission shows a sharply marginated mass of 6.6 cm in diameter in the left temporal and parietal lobes and compressing the surrounding parenchyma. The left lateral cerebral ventricle is compressed. The lesion had a high-density region in the dorsal aspect indicating hemorrhage. (b) Axial enhanced CT image shows a massive lesion like a cyst with enhancement. (c) Digital subtraction angiography (DSA) of the frontal view shows tumor staining via the middle cerebral artery. (d) DSA of the lateral view shows tumor staining and no arteriovenous shunts.
