A nodular hyperdense frontotemporal image anterior to a large left side predominantly temporal hematoma associated to edema and signs of subfalcine and transtentorial herniation, and a midline shift of approximately 6 mm [Figure 1]. An urgent magnetic resonance imaging (MRI) revealed aneurysm of 2, 5 cm in diameter, with partially thrombosed content associated to a large left temporal hematoma [Figure 2].
