本回顾性研究的目的是探讨上矢状窦附近皮质静脉周围囊性结构的数量和大小与皮质静脉周围钆基造影剂（GBCA）泄漏的关系。190例患者（91名男性和99名女性）在静脉注射GBCA后4小时进行扫描，作为内淋巴积液的诊断检查，6例GBCA渗漏患者比先前提出的37.3岁的渗漏阈值年龄要小。同时纳入6例年龄匹配且无渗漏的患者作为参考。此外，我们纳入了8例年龄大于假设阈值37.3岁的无渗漏病例，以及8例年龄匹配的GBCA渗漏到脑脊液间隙的患者。28例患者（年龄32-60岁，男13例，女15例），计数囊肿数量，测量囊肿大小。有和无GBCA渗漏组旁矢状区皮质静脉周围平均囊肿数分别为4.29±1.77个和1.79±1.05个（P = 0.0001）。有和无GBCA渗漏组最大囊肿的平均大小分别为8.89±3.49 mm和5.69±2.29 mm （P = 0.009）。蛛网膜下腔有GBCA渗漏的患者，其上矢状窦附近静脉周囊性结构的数量和大小均大于无渗漏者。需要进一步研究这些副矢状面囊性结构的组织学和功能细节。
The purpose of this retrospective study was to investigate the relationship between the number and size of cystic structures around the cortical veins near the superior sagittal sinus and the leakage of gadolinium-based contrast agent (GBCA) around the cortical veins. Of 190 patients (91 male and 99 female), that were scanned at 4 h after an intravenous injection of GBCA as a diagnostic examination for endolymphatic hydrops, 6 patients with GBCA leakage were younger than the previously proposed threshold age of 37.3 years for leakage. Six age-matched patients without leakage were also included for reference. In addition, we included 8 cases without leakage that were older than the hypothesized threshold of 37.3 years, as well as 8 age-matched patients with GBCA leakage into the cerebrospinal fluid space. The number of cysts was counted and the sizes were measured in these 28 patients (age: 32–60 years old, 13 men and 15 women). The mean number of cysts surrounding the cortical veins in the parasagittal region was 4.29 ± 1.77 vs. 1.79 ± 1.05 (P = 0.0001) in the subjects with and without GBCA leakage, respectively. The mean size of the largest cysts was at 8.89 ± 3.49 mm vs. 5.69 ± 2.29 (P = 0.009) in the subjects with and without GBCA leakage, respectively. The number and size of the perivenous cystic structures near the superior sagittal sinus is greater in subjects with GBCA leakage into the subarachnoid space compared with those without leakage. Future research regarding the histological and functional details of these parasagittal cystic structures is needed.
