Persistent primitive hypoglossal artery (PPHA) which is a persistent carotid-basilar anastomosis is a rare vascular anomaly. It is usually found incidentally. Fenestrations of cerebral arteries are uncommon. Herein we present a case of PPHA with fenestration of posterior cerebral artery. A 28 year old man was admitted to our hospital with complaints of dizziness and temporary loss of vision. Neurological examination revealed no abnormal findings. The patient was further evaluated with CT and MR angiography. To our knowledge, the case we reported is the first case in the literature with PPHA and fenestration of posterior cerebral artery. The detection of PPHA and associated vascular anomalies and diseases are important before surgical and interventional procedures. CT and MR angiography are much safer diagnostic alternatives in the detection of PPHA and fenestrations. When PPHA is detected, attention should be given to the coexistent posterior circulation anomalies.
持续性原始舌下动脉（PPHA）是一种持续存在的颈动脉-基底动脉吻合，是一种罕见的血管异常。它通常是偶然发现的。脑动脉开窗并不常见。在此，我们报告一例伴有大脑后动脉开窗的PPHA病例。一名28岁男性因头晕和短暂视力丧失入院。神经系统检查未发现异常。对该患者进一步进行了CT和磁共振血管造影检查。据我们所知，我们报告的该病例是文献中首例伴有大脑后动脉开窗的PPHA病例。在进行手术和介入操作之前，检测PPHA以及相关的血管异常和疾病很重要。CT和磁共振血管造影在检测PPHA和开窗方面是更安全的诊断选择。当检测到PPHA时，应注意并存的后循环异常。
