摘要

我们提出一例松果体动静脉畸形（AVMs）与脑室内出血和脑积水在一个老年患者。成像显示松果体区一个7毫米的病灶，由后外侧脉络膜动脉（PLChA）供给并汇入鼻窦汇合处。发现PLChA远端2毫米血流相关动脉瘤。以直线加速器为基础的立体定向放射外科治疗病灶和动脉瘤。四个月后，磁共振血管造影显示动脉瘤消失。患者无出血4年，直至死亡。本病例具有罕见的特征：迟发性出血，对血流相关动脉瘤进行放疗，放疗后动脉瘤迅速消退。

Hemorrhaged pineal arteriovenous malformation in an older adult patient: Case report and literature review

We present a case of a pineal arteriovenous malformations (AVMs) with intraventricular hemorrhage and hydrocephalus in an older adult patient. Imaging revealed a 7 mm nidus of the pineal region, fed by the posterolateral choroidal arteries (PLChA) and draining into the confluence of the sinuses. A 2 mm distal flow-related aneurysm of the PLChA is identified. Linear-accelerator-based stereotactic radiosurgery was used to treat the nidus and aneurysm. Four months later, MR angiography revealed the disappearance of the aneurysm. The patient remained rebleed-free for 4 years until death. This case features rare elements: late-onset hemorrhage, radiotherapy for flow-related aneurysms, and rapid postirradiation aneurysm resolution.
