Abstract
Objective To investigate the clinical and imaging characteristics of tentorial dural arteriovenous fistulae (DAVF) which presented as ischemic damage in posterior circulation. Methods The clinical and imaging data of 3 tentorial DAVF patients presented as ischemic damage in posterior circulation were analyzed retrospectively. Results The onset in this group was various forms. The manifested symptoms of the 3 cases were vertigo, nausea, vomiting, pathological lateral ataxia and horizontal nystagmus. One case presented with crossed sensory disturbance, mild medulla oblongata paralysis and incomplete Horner's syndrome. Skull magnetic resonance imaging (MRI) was showed ischemic damage in cerebellum in 3 cases and brain stem in 1 cases. The lesions were long T1, long T2 changes and high signal on diffusion weighted imaging. MRI contrasted scan in 2 cases also found enhancement of lesions and multiple abnormal curved enhanced blood vessels. The 3 cases received digital subtraction angiography (DSA) examination and all found DAVF in tentorium of cerebellum. Conclusions Tentorial DAVF may cause ischemic damage in cerebellum and brain stem. MRI may show enhancement of lesions and abnormal blood vessels. Definite diagnosis can depends on DSA examination.关键词
