Asymmetric ischiopubic synchondrosis syndrome (van Neck-Odelberg disease)

Case contributed by Dr Javier Salguero

Presentation

An child with chronic left hip pain

Patient Data

Age: 5 year old
Gender: Male

There is an expansile lesion of the inferior ischial and pubic rami that resembles a lytic bone mass (chondroid matrix)

Case Discussion

This is an important variant that we as radiologists have to take in consideration. The ischiopubic synchondrosis (IPS) is the junction between the inferior ischial and pubic rami and is principally composed of hyaline cartilage. Is a temporal joint occurring in childhood prior to fusion of the ischial and pubic bones. With skeletal maturation, like all synchondroses, it becomes thinner and then obliterates, either due to bony union or synostosis.
