Hippocampal venous congestion is a rare complication associated with cavernous sinus dural arteriovenous fistulas (CS-DAVFs).
A 74-year-old woman was admitted to the hospital with a swollen left eye. Isolated lesions were found in the left hippocampus and the middle cerebellar peduncle. Cerebral angiography revealed retrograde venous drainage of the bilateral inferior petrosal sinuses from the left CS-DAVF. The patient underwent transcatheter arterial embolization, resulting in complete resolution of the hippocampal lesions and neurological symptoms.
Hippocampal injury is a rare complication of CS-DAVF. Attentive diagnosis and treatment can effectively prevent adverse consequences.
海绵窦硬脑膜动静脉瘘（CS-DAVFs）可并发罕见的海马静脉淤血。
一名 74 岁女性因左眼肿胀而入院。在左侧海马体和小脑中脚发现孤立性病变。脑血管造影显示双侧岩下窦从左侧 CS-DAVF 逆行静脉引流。患者接受了经导管动脉栓塞治疗，左侧海马病变和神经症状完全缓解。
海马损伤是 CS-DAVF 的罕见并发症。及时诊断和治疗可以有效预防不良后果。
