van Neck-Odelberg disease: a common but poorly known and often misdiagnosed condition.

van Neck-Odelberg disease, a condition involving the ischiopubic synchondrosis in children, is a commonly encountered but poorly known ailment, which is now considered a normal variant. Symptoms can include pain, discomfort, and fever, leading to van Neck-Odelberg disease often being discovered in the context of patients presenting with non-specific clinical manifestations. In this essay, we describe what is currently known about van Neck-Odelberg disease and illustrate the condition using images acquired from multiple patients, with some using multiple imaging techniques from the same patients. Awareness of van Neck-Odelberg disease is essential for radiologists who are involved in the treatment of children, as well as for paediatricians, to prevent misdiagnosis and unnecessary invasive procedures for what is a benign and self-resolving condition.
