Radiation-associated aneurysms are rare, difficult to treat, and associated with high morbidity and mortality when ruptured, compared with aneurysms unrelated to radiation treatment. We present a 16-year-old patient with a radiation-induced intracranial aneurysm arising from the left posterior inferior cerebellar artery (PICA), 10 years following radiotherapy for medulloblastoma. The patient successfully underwent endovascular coil embolization of the parent artery across the neck of the aneurysm. CT angiography and MRI in the days following the procedure demonstrated maintained flow in the anterior and lateral medullary PICA segments with no brainstem infarct.

放射治疗引起的颅内动脉瘤伴有成髓细胞瘤的儿童急性出血。

与放射治疗无关的动脉瘤相比,放射相关的动脉瘤很少见,难以治疗,破裂时的发病率和死亡率较高。我们介绍了一名16岁的患者,该患者在放疗髓母细胞瘤后10年因左小脑下后动脉(PICA)放射致颅内动脉瘤。患者成功地对整个动脉瘤的颈部进行了主动脉的血管内线圈栓塞术。术后几天的CT血管造影和MRI证实前,外侧PICA节段中血流保持恒定,无脑干梗塞。
