Purpose To investigate the relationship between aponeurotic expansion of supraspinatus tendon and disorders of biceps brachii long head (LHB), supraspinatus and subscapularis tendons. Methods Images of 3.0 T shoulder magnetic resonance images (MRI) of a total of 154 patients and 157 shoulders (3 cases with bilateral imaging) between the ages of 18–45 were retrospectively evaluated for the presence of aponeurotic expansion. When identified it was further categorized according to its thickness. Tendinopathy and tears of LHB, supraspinatus and subscapularis tendons and LHB subluxations were evaluated individually. Statistical analyses were performed using Chi-square, Fisher's exact, Mann–Whitney U and Kruskall–Wallis tests. Odds ratio and multiple logistic regression analyses were performed when applicable. p Results A total of 82 male and 72 female cases with a mean age of 34 (±8.2) were included. Aponeurotic expansion could be identified in 31 cases (19.8 %). MRI findings for LHB disorders in this group was significantly higher (p = 0.01). The adjusted odds ratio of having LHB tendinopathy in the presence of aponeurotic expansion was 3.25 (% 95 CI:1.29−8.19). No significant correlation was found between presence of aponeurotic expansion and subscapularis or supraspinatus tendon disorders (p = 0.66 and p = 0.792 respectively). Age was a significant variable for disorders of all three tendons (p Conclusion On 3.0 T MRI, findings of LHB tendon disorders were significantly more common in cases with aponeurotic expansion of supraspinatus tendon. This anatomical variation may have an unrecognized clinical significance.

To reveal the MR enterography (MRE) findings that distinguish backwash ileitis (BWI) from terminal ileitis due to Crohn's disease (CD) and to determine the usability of barium studies manifestations (ileocecal valve (ICV) gaping, terminal ileum dilatation) in MRE for the diagnosis of BWI in ulcerative colitis (UC) patients by pointing at the diagnostic performance of these imaging findings.The study population consisted of patients who were diagnosed as ulcerative colitis (UC), and underwent 1.5 T MRI between August 2011 and November 2017 to rule out small bowel involvement. The matched controls were comprised of Crohn's patients examined at the same period. Ileocolonoscopic/ histopathologic findings were accepted as reference standard. Mural/extramural changes in bowel segments, ileocecal valve (ICV) gaping, terminal ileum dilatation, restricted diffusion and anatomical extent of involvement were evaluated. In UC patients, the association between ICV gaping and terminal ileum dilatation and BWI was assessed by χ2 test. The diagnostic accuracy of these two findings in BWI was determined.Sixty patients were included in the study (30 UC; 30 CD; mean age, 43 years in both groups). Ileocecal valve gaping and terminal ileum dilatation were significantly more frequent among BWI patients (p 0.001) in UC. Patients with BWI showed a higher rate of pancolitis (88.9%). Median terminal ileum wall thickness was found to be significantly greater in patients with CD (p 0.001).In patients with definite diagnosis of UC, ileocecal valve gaping and terminal ileum dilatation suggest the development of BWI. However, these findings cannot be use to differentiate cause of terminal ileitis in patients with unconfirmed diagnosis and do not give reliable information about the causative factor of ileitis.
