Van Neck–Odelberg osteochondritis versus osteoarthritis or tumoral disease: A case series

Introduction: Enlarged ischiopubic synchondrosis is a frequent finding in radiology. Although it is a normal growth phenomenon, its tumor-like appearance may cause diagnostic confusion. Case Series: We report two cases of pediatric patients presenting with unilateral pelvic pain. Magnetic resonance imaging findings revealed asymmetrical ischiopubic synchondrosis enlargement, mimicking tumoral conditions. Conservative management resulted in clinical improvement. Conclusion: Recognizing this radiological appearance is crucial to avoid unnecessary interventions and differentiate it from more severe pathologies.
