摘要

A 54-year-old man presented with gait disturbances, urinary incontinence, and headache for 6 months. Head computed tomography indicated several high-density mass lesions in the quadrigeminal cistern, causing occlusive hydrocephalus. Digital subtraction angiography confirmed tentorial dural arteriovenous fistulae (AVF). Transarterial embolization (TAE) achieved complete angiographic resolution. However, acute occlusive hydrocephalus worsened, necessitating endoscopic third ventriculostomy (ETV). The patient was discharged without new symptoms and no hydrocephalus recurrence at six-month follow-up. Hydrocephalus is rare in patients with dural AVF and mostly resolves spontaneously after treatment; however, if thrombosis and enlargement of the varix occur after treatment, acute occlusive hydrocephalus can develop.
