title: "Kissing" aneurysms of the internal carotid artery treated by coil embolization.
abstract: A 62-year-old female complaining of sudden severe headache was referred to our stroke center in consultation. Computed tomography showed diffuse spread of thick subarachnoid hemorrhage to the basal cistern and both sylvian fissures, and digital subtraction angiography showed kissing aneurysms arising in the left lateral and occipital directions in the C(1) portion of the internal carotid artery (ICA). The anterior choroidal artery was situated between the two aneurysms, and another small branch originating from the dome of the distal aneurysm was confirmed as a duplicated middle cerebral artery (MCA). Endovascular treatment was successfully performed to spare the two vessels involved. This case of kissing aneurysms and ICA-duplicated MCA is very rare, and presents difficulties for both surgical and endovascular treatments.
