Cavernous sinus dural arteriovenous fistula complicated by hippocampus venous congestion: A case report.

BACKGROUND

Hippocampal venous congestion is a rare complication associated with cavernous sinus dural arteriovenous fistulas (CS-DAVFs).

CASE DESCRIPTION: 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.

CONCLUSION

Hippocampal injury is a rare complication of CS-DAVF. Attentive diagnosis and treatment can effectively prevent adverse consequences.
