Primitive proatlantal intersegmental artery (PPIA) is rare and can be divided into types I and II. PPIAs can be associated with some anatomical variations and vascular diseases. However, no case of PPIA combined with moyamoya disease (MMD) has been reported. Here, we reported such a case. A 54-year-old man experienced headache for 1 month. The results of the neurological examinations were unremarkable. Magnetic resonance angiography and digital subtraction angiography revealed a right type I PPIA with MMD. The PPIA serves as an important collateral path for MMD patients. Because the patient only experienced headache, he was discharged and underwent follow-up observation. This case indicates that, rarely, PPIA can be associated with MMD and serve as a collateral vessel for MMD patients.
原始寰椎前节间动脉（PPIA）较为罕见，可分为I型和II型。PPIA可伴有一些解剖变异和血管疾病。然而，尚无PPIA合并烟雾病（MMD）的病例报道。在此，我们报告了这样一例病例。一名54岁男性头痛1个月。神经系统检查结果无明显异常。磁共振血管造影和数字减影血管造影显示右侧I型PPIA合并MMD。PPIA是MMD患者重要的侧支循环途径。由于该患者仅出现头痛症状，故出院并接受随访观察。该病例表明，PPIA极少可与MMD相关联，并可作为MMD患者的侧支血管。
