Case report: Multimodality imaging of van Neck-Odelberg disease

Abstract

Synchondrosis ischiopubic syndrome (SIS), also known as van Neck-Odelberg disease, is a syndrome characterized by an atypical ossification pattern of the ischiopubic synchondrosis. Its radiological features may mimic stress fracture, neoplasm, osteomyelitis, or posttraumatic osteolysis, causing problems in diagnosis, sometimes leading to unnecessary workup. We report two cases in which the correlation between the clinical and multimodality imaging data enabled the correct diagnosis of SIS.
