    BackgroundAn aneurysm of distal lenticulostriate artery is very rare. The natural course and management of this rare aneurysm are not clear.Case DescriptionAn 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.ConclusionAn aneurysm at this location can show dynamic changes based on radiological findings. Close radiological observation is necessary.
