Frequency of anatomical variation of the sacroiliac joint in asymptomatic young adults and its relationship with sacroiliac joint degeneration

Introduction To evaluate the variations of the sacroiliac joint (SIJ) in asymptomatic young adults and their relationship to SIJ degeneration. Materials and Methods A total of 860 SIJs were retrospectively evaluated in 430 abdominal computed tomographies (CT) of abdominal pain cases. The study population consisted of 430 patients (176 female, 254 male) aged 20-45 years with abdominal pain. The anatomical variations of the SIJ were classified as (1) accessory sacroiliac joint, (2) iliosacral complex, (3) bipartite iliac bony plate, (4) semicircular defects, (5) crescent-like iliac bony plate, and (6) ossification center. The CT findings of SIJ degeneration included joint space narrowing, sclerosis, subcortical cysts, vacuum phenomenon, and osteophytes. Chi-square and cross tabulation tests were used for statistical analysis. Results The iliosacral complex was the most common (bilateral) anatomical variation (7.7%, n = 66). A total of 71 SIJ degenerations were detected in cases with anatomical variations. They were determined in 22 (2.6%) iliosacral complex, 19 (2.2%) bipartite iliac bony plate, 15 (1.7%) accessory sacroiliac joint, 6 (0.7%) semicircular defect, 5 (0.6%) crescent-like iliac bony plate, and 4 (0.5%) ossification center cases. Conclusion We found that iliosacral complex was the most common SIJ variation in asymptomatic young adults and also that there was significantly more SIJ degeneration among subjects with anatomical variations of the SIJ than those without. SIJ degeneration was most common in subjects with the iliosacral complex variation

Anatomical variations of paranasal sinus and ethmoid roof type on computed tomography in patients admitted to the emergency department with migraine headache

In this study, we aimed to evaluate the anatomical variations of paranasal sinus on computed tomography (CT) in patients admitted to the emergency department due to migraine. Patients who had brain CT with a diagnosis of migraine admitted to our emergency department with a complaint of headache between June2018 and January2019 were retrospectively reviewed. Fifty-five migraine headache patients and 55 control group patients were included to this study. According to the Keros classification, the ethmoid roof height was type1 in 25, type2 in 15 and type3 in 15 of the patients with migraine. In the control group, 28 patients had type1, 14 patients type2, 13 patients type3 ethmoid roof. Anatomical variations in patients with migraine: Nasal septal deviation in 14 cases, Agger nasi cell in 6, pneumatization posterior sella turcica 1, prominent ethmoidal bulla 4, Haller cell 3, nasal septal spur 5, concha bullosa 15, pneumatized anterior clinoid process in 6, uncinate cells 4, Onodi cells 7, pneumatized crista galli 7, presence of maxillary sinus 1, frontal sinus aplasia 5, sphenoid sinus agenesis 2, frontal bulla 2, frontal sinus hyperplasia 2, paradoxical middle turbinate 1. As a result,there is no significant difference was found between the migraine patients and the control group in terms of ethmoid roof height according to Keros classification.In the control group and migrane cases,there was a significant difference in the frequency of pneumatization posterior to floor of sella turcica, nasal septal spur, uncinate cells and the presence of maxillar sinus anatomic variations.
