Abstract

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.

How strong is the evidence?

Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
