Lenticulostriate artery aneurysm （LSAs） is a relatively rare type of intracranial aneurysms， and rupture of LSAs is a rare cause of deep intracerebral hemorrhage. It may have the manifestation of intraparenchymal hemorrhage in the basal ganglia and is easily misdiagnosed as nonaneurysmal hypertensive intracerebral hemorrhage， causing a delay in treatment. With the rapid development of imaging techniques in recent years， the detection rate of LSAs is gradually increased. The development and progression of LSAs are often affected by various factors， but its specific etiology and natural disease course remain unknown. At present， open surgical clamping， endovascular treatment， and gamma knife surgery are the main treatment methods for LSAs. Most reports on the treatment of LSAs are described by case reports and small case series， and there are still controversies over the efficacy and prognosis of different treatment methods. This article reviews the latest research advances in LSAs and its treatment strategies. ［Journal of International Neurology and Neurosurgery, 2023, 50(6): 84-91］
