背景海绵窦（CS）硬脑膜动静脉瘘（dAVF）与脑干增强病变是罕见的，和脑干增强病变可能是不可逆的指示。磁振造影显示脑桥有单侧强化病灶，因此怀疑为恶性脑肿瘤。脑血管造影显示CS-dAVF伴脑干逆行软脑膜静脉引流（RLVD）。经静脉栓塞与选择性弹簧圈栓塞RLVD进行，症状和影像学显着improved. ConclusionsDAVF RLVD应提到的脑干增强病变的鉴别诊断。RLVD的经静脉栓塞和选择性弹簧圈栓塞是治疗CS-dAVF的有效方法，单侧增强脑干病变可能是可逆的。
BackgroundCavernous sinus (CS) dural arteriovenous fistula (dAVF) with an enhanced lesion in the brainstem is rare, and an enhanced lesion in the brainstem might be indicative of irreversibility.Case DescriptionA 77-year-old woman presented with double vision and ataxia. Magnetic resonance imaging showed a unilateral enhancement lesion in the pons, so a malignant brain tumor was suspected. A cerebral angiogram revealed CS-dAVF with retrograde leptomeningeal venous drainage (RLVD) to the brainstem. Transvenous embolization with selective coil embolization of RLVD was performed, and the symptoms and imaging improved dramatically.ConclusionsDAVFs with RLVD should be mentioned as a differential diagnosis of enhanced lesions in the brainstem. Transvenous embolization with selective coil embolization of RLVD was effective for the treatment of CS-dAVF, and a unilateral enhanced brainstem lesion may be reversible.
