Lenticulostriate artery aneurysms are rare, can be difficult to diagnoze, and when they rupture they are often associated with deep intraparenchymal hemorrhages. In particular, fusiform, dissecting aneurysms of a distal lenticulostriate artery are extremely rare. Typically, they are usually associated with underlying systemic conditions such as systemic lupus erythematosus, moyamoya disease, and substance abuse. Given their usual small size and location, these aneurysms may be difficult to detect with angiography and can be challenging to treat with either endovascular or microsurgical techniques. We provide background information, review the existing treatment experiences reported in the literature, and present a discussion regarding the optimal management using an illustrative clinical vignette. Parent artery obliteration can be a safe and effective treatment in these rare aneurysms.
纹状体动脉动脉瘤很少见，诊断困难，破裂时常伴有深部脑实质内出血。特别是，远端纹状体动脉的梭形、夹层动脉瘤极为罕见。通常，它们通常与系统性红斑狼疮、烟雾病和药物滥用等潜在系统性疾病有关。由于它们通常体积较小且位置较深，这些动脉瘤可能难以通过血管造影检测，并且用血管内或显微手术技术治疗也具有挑战性。我们提供背景信息，回顾文献中报道的现有治疗经验，并通过一个说明性临床病例讨论最佳治疗方法。在这些罕见的动脉瘤中，主干动脉闭塞术是一种安全有效的治疗方法。
