| 目的 通过影像学研究自发性脑脊液鼻漏伴发空蝶鞍的发生率。方法 22例自发性脑脊液鼻漏患者均接受MR检查,其中18例接受CT检查;将影像学所见漏口与鼻内镜手术结果进行比较。结果 手术证实22例患者共24处漏口,其中21例为单发,1例有3处漏口。18例CT检查共显示11处骨质缺损,显示率为55.00%(11/20)。22例冠状面MR T2WI共显示13处漏口,显示率为54.17%(13/24),冠状面水成像序列上共显示20处漏口,显示率为83.33%(20/24)。17例CT(94.44%)显示蝶鞍扩大并充满脑脊液样密度影;16例MR(72.73%)呈完全空蝶鞍表现,6例(27.27%)呈部分空蝶鞍表现。另外,17例MR(77.27%)冠状面水成像序列显示视神经蛛网膜下腔增宽。完全空蝶鞍组与部分空蝶鞍组患者病程之间差异无统计学意义(P=0.60)。结论 自发性脑脊液鼻漏患者均伴有空蝶鞍,空蝶鞍可作为自发性脑脊液鼻漏辅助诊断的有力旁证。 |

| Objective To study the prevalence of empty sella in spontaneous cerebrospinal fluid rhinorrheas patients with CT and/or MRI. Methods The Imaging data of 22 patients with spontaneous cerebrospinal fluid rhinorrheas (MR in 22 patients and CT in 18 patients) were retrospectively analyzed. Leaks identified with CT and MRI were compared with that observed through endoscopic sinus surgery. Results Twenty-four leaks were confirmed with endoscopic sinus surgery in 22 patients,one of which had 3 leaks. In 20 leaks of 18 patients, CT demonstrated 11 bone defects (11/20, 55.00%). In 24 leaks of 22 patients, coronal MR T2WI displayed 13 leaks (13/24, 54.17%), and coronal T2WI MR cisternography (MRC) revealed 20 leaks (20/24, 83.33%). The sella turcica were enlarged and filled with cerebrospinal fluid on CT in 17 patients (94.44%). MRI showed abnormal increase of cerebrospinal fluid inside the sella and the compressed pituitary gland in all the 22 patients, of which 16 (72.73%) showed complete empty sella and 6 (27.27%) in partial empty sella. Coronal MRC demonstrated the enlargement of perioptic subarachnoid space in 17 patients (77.27%). In addition, there was no statistical significance of disease course between complete empty sella and partial empty sella (P=0.60). Conclusion The imaging demonstrates the spontaneous cerebrospinal fluid rhinorrheas are all accompanied with empty sella, indicating that empty sella can be regarded as a significant accompanying imaging feature for the diagnosis of spontaneous cerebrospinal fluid rhinorrheas. |
