Objective: To explore the clinical and imaging features of ischiopubica osteochondritis(Van Neck disease). Methods: Clinical and imaging features of 23 cases with Van Neck disease were reviewed and X-ray films of 100 cases examined for other reasons were randomly chosen. Results: In the 23 cases of disease group, 16 cases were unilateral and 7 cases were bilateral. X-ray examination showed local prominence between ischium and pubis in all cases. Lamellar changes of the bone inhomogeneous in density with round translucence were found in 8 cases accompanied with intact cortex. Mild osseous hyperplasia was found in 8 cases without changes of periosteum and soft tissues. CT examination of 8 cases presented with local prominence between ischium and pubis, translucence, cataclasm, discontiguous osteal cortex with irregular ends, sclerotic medullary cavity of boney surroundings, but no sequestration and changes of periosteum and soft tissues. The above-mentioned X-ray features appeared in 14 cases among normal group, bilateral in 3 cases. Conclusion: Imaging features of Van Neck disease were typical, which can help correct diagnosis and differential diagnosis combined with the clinical manifestation.
