Aneurysm of lenticulostriate artery in a patient presenting with hemorrhage in the caudate nucleus and lateral ventricle-delayed appearance and spontaneous resolution

Motohiro Nomura et al. Surg Neurol Int. .

Abstract

Background: An aneurysm of distal lenticulostriate artery is very rare. The natural course and management of this rare aneurysm are not clear.

Case description: An 81-year-old woman developed consciousness disturbance. Computed tomography revealed hemorrhage in the right caudate nucleus and lateral ventricles. Three-dimensional computed tomographic angiography demonstrated only an aneurysm at the basilar artery. On angiography, on the sixth day, an aneurysm at the right lenticulostriate artery was demonstrated. Then, the aneurysm disappeared on three-dimensional computed tomographic angiography on the 15th day. Subsequent radiological examinations revealed no vascular anomaly in the right lenticulostriate artery.

Conclusion: An aneurysm at this location can show dynamic changes based on radiological findings. Close radiological observation is necessary.

Keywords: Cerebral aneurysm; delayed appearance; lenticulostriate artery; ruptured; spontaneous obstruction.
