This study aims to describe the uncommon intraosseous migration of rotator cuff calcific tendinitis and evaluate these cases concerning demographic characteristics, associated pathologies, and radiological findings. Materials and methods: This retrospective study, conducted between January 2021 and September 2024, reviewed 3.755 shoulder MRI scans. Exclusions included motion artifacts, pediatric cases, trauma or surgery history, and infections. Two radiologists independently evaluated cases of calcific tendinitis and intraosseous migration, analyzing findings against demographic data and related pathologies. Results: Out of 3.000 scans, calcific tendinitis was found in 8.17% of cases. Intraosseous complications occurred in 0.5% of the total population and 6.12% of tendinitis cases. Most calcific tendinitis patients (73.77%) were female, with 86.67% of intraosseous cases being women (p=0.211 (Fisher’s Exact Test)). The supraspinatus tendon was most frequently affected (63% of cases), with effusion being the most common pathology (55%). Patients with intraosseous complications showed higher rates of supraspinatus and infraspinatus involvement (both 73%) compared to those without complications (63% and 36%, respectively), and the difference was statistically significant (Fisher’s Exact Test, p=0.005 for infraspinatus). Conclusion: Calcific tendinitis can present rare intraosseous extensions, requiring careful imaging for accurate diagnosis. MRI and CT play crucial roles in identifying these cases. Untreated cases show persistent complications, while ultrasound-guided injections provide effective treatment. Proper differential diagnosis is necessary as calcific tendinitis may mimic tumors. Early diagnosis and appropriate treatment of intraosseous complications are essential. Future studies should explore larger populations and long-term follow-up for better evaluation of prognosis and outcomes.}, number={3}, publisher={Pamukkale Üniversitesi}
