Ischiopubic Synchondrosis Asymmetry: An Underestimated Cause of Pelvic Pain in Pediatric Patients

Abstract

Ischiopubic synchondrosis asymmetry is a benign and transient variant of the normal ossification process, typically observed in the pediatric age group, which may present as unilateral pelvic pain. We report the clinical case of an 11-year-old boy with a three-month history of right groin pain, without any history of trauma. Pelvic radiography revealed an ovoid radiolucent lesion with slightly sclerotic margins, located in the right ischiopubic ramus, corresponding to the region of the ischiopubic synchondrosis. Magnetic resonance imaging showed hypertrophy and edema of the corresponding synchondrosis, findings consistent with a skeletal developmental variant. Recognition of this benign entity is essential to avoid invasive investigations or unnecessary treatments. The patient achieved complete symptom resolution with conservative management.
