【摘要】：目的探討以眼部癥狀首診的良性顱內(nèi)壓增高(BIH)患者的眼部MRI影像特點。設(shè)計回顧性病例系列。研究對象65例經(jīng)臨床確診的良性顱內(nèi)壓增高病例。方法回顧性分析患者臨床資料及顱腦、眼眶MRI數(shù)據(jù),統(tǒng)計各主要影像征象在本組患者中出現(xiàn)的比例,比較各影像征象在特發(fā)性顱內(nèi)壓增高(IIH)、顱內(nèi)靜脈竇血栓形成(CVST)及細胞數(shù)增多的BIH之間的差異及MRI診斷與眼底鏡檢查結(jié)果的差異。主要指標顱腦、眼眶MRI影像表現(xiàn)。結(jié)果 65例良性顱內(nèi)壓增高患者中,多數(shù)存在空蝶鞍(78.5%)、視神經(jīng)周圍蛛網(wǎng)膜下腔增寬(74.1%),其次是視乳頭隆起(55.9%),視神經(jīng)走行迂曲(37.3%)、眼球后壁后鞏膜變扁平(34.0%)和視神經(jīng)本身(粗細、信號、強化程度)異常(33.9%),小腦扁桃體下疝(7.7%)。視神經(jīng)周圍蛛網(wǎng)膜下腔增寬在IIH組發(fā)生率與CVST和細胞數(shù)增多的BIH均存在差別(χ~2=10.161,P=0.001;χ~2=6.065,P=0.014)。與眼底鏡結(jié)果比較MRI檢測視乳頭水腫的敏感度52.8%,特異度58.3%。結(jié)論除空蝶鞍外,視神經(jīng)周圍蛛網(wǎng)膜下腔增寬是以眼部癥狀首診的BIH患者常見MRI表現(xiàn),可單獨或合并多種MRI征象出現(xiàn)。
[Abstract]:Objective to investigate the features of ocular MRI in patients with benign intracranial hypertension (BIH) who were first diagnosed with ocular symptoms. Design retrospective case series. Participants 65 cases of benign intracranial hypertension confirmed by clinical diagnosis. Methods the clinical data, craniocerebral and orbital MRI data were analyzed retrospectively. To compare the difference of various imaging signs between (CVST) and BIH of intracranial venous sinus thrombosis (CVST) in (IIH), with increased intracranial pressure, and the difference between MRI diagnosis and fundus endoscopy. Main outcome measures Imaging of craniocerebral and orbital MRI. Results in 65 patients with benign intracranial hypertension, most of them had empty Sella (78.5%), subarachnoid space around optic nerve (74.1%), optic papilla protuberance (55.9%), optic nerve traverse and detour (37.3%), posterior sclera flattening (34.0%) and optic nerve itself (thick and thin). Signal intensity was abnormal (33.9%) and cerebellar subtonsillar hernia (7.7%). The incidence of subarachnoid space widening around the optic nerve in IIH group was significantly higher than that in CVST group and BIH with increased cell count (蠂 ~ 2 ~ 2 ~ (2) 10.161 ~ (-1) P ~ 0. 001; 蠂 ~ (2) n = 6.065 ~ 0. 014). The sensitivity and specificity of MRI in the detection of papillary edema were 52.8% and 58.3% respectively. Conclusion the enlargement of subarachnoid space around the optic nerve is a common MRI manifestation in BIH patients with ocular symptoms except empty Sella, and may appear alone or in combination with multiple MRI signs.
