Objective: To assess the incidence of the sacroiliac joint vacuum phenomenon (SIJ VP) in paediatric patients and the relationship between the presence of VP and clinical factors such as age, sex and body mass index (BMI). Methods: We retrospectively reviewed clinical data and imaging findings of 60 patients who underwent abdominopelvic CT (AP CT) between January and June 2015. Patients were divided into VP group and non-VP group based on the presence/absence of VP, and the groups were compared. In addition, other degenerative changes in the SIJ were recorded. Results: The SIJ VP was detected in 19 (31.6%) patients. There were no significant differences in sex distribution between VP and non-VP groups (p 5 0.781). The age of the VP group was significantly higher than that of the non-VP group (p , 0.001). After adjusting the BMI for age, there was no significant association between high BMI and the presence of SIJ VP (p 5 0.326). Other degenerative changes were not noted in any of the patients. Conclusion: The SIJ VP is not an uncommon finding in paediatric patients. The prevalence of SIJ VP in paediatric patients is similar to its prevalence in adults. The SIJ VP is related to patient age, but not to sex or BMI in children and young adolescents. Advances in knowledge: AP CT can provide information about the SIJ, if it is required to assess the SIJ in paediatric patients. INTRODUCTIONThe sacroiliac joint vacuum phenomenon (SIJ VP) is not an uncommon finding in adults.1-3 When radiologists face abdominopelvic CT (AP CT), little attention is paid to the SIJ. However, AP CT can provide information about the SIJ, if we attempt to observe the SIJ.1-3 The SIJ VP has been reported in approximately 31-34% of adults. 1,4 In addition, it is observed more frequently in females and in patients older than 60 years.1 Moreover, it is considered an age-related morphological variant, and obesity is believed to affect such degenerative changes in the SIJ. 4 To our knowledge, there has been no report on the SIJ VP among only paediatric patients, and data are lacking on its prevalence and clinical significance in this group. Based on our experience of reviewing AP CT images, we recognized that the SIJ VP is not unusual among paediatric patients as well. We hypothesized that the prevalence of SIJ VP among paediatric patients is similar to that among adults. The present study aimed to investigate the radiological findings of the SIJ using AP CT images and assess the incidence of the SIJ VP among paediatric patients. Furthermore, the

“…The lower two-thirds (synovial area) of the joint is spared. However, ossification of the joint capsule on the anterior surface of the joint can occur, which sometimes resembles fusion of the SI joints on anteroposterior pelvic radiographs and may mistakenly be interpreted as postinflammatory ankylosis of the joint (grade 4 sacroiliitis) 9 . Computed tomography (CT) can be helpful in these cases by demonstrating the normal aspect of the joint space and bony margins together with the presence of the anterior capsular ossification 9 .…”

“…The radiologic features of spine involvement in AS and DISH are so different (13,14) that in patients with coexisting spondylarthropathy and DISH, it is possible to recognize the changes due to each disease (15-17). AS has typical inflammatory sacroiliac joint lesions, while DISH may give images of partial sacroiliac joint fusion, but as a consequence of large anterior capsular bridging (18). Our patient had grade 4 bilateral sacroiliitis and typical signs of AS, without any sign of DISH in her spine.…”
