Presentation
Right hip pain. No trauma.
Patient Data
Irregularity of the right ischiopubic synchondrosis.
No fracture or avulsion.
Edema centered on the previously demonstrated ischiopubic synchondrosis with surrounding soft-tissue edema.
Case Discussion
The right ischiopubic synchrondrosis is expanded on the plain film. This can happen for a number of reasons, but is usually normal. Irregularity of the synchondrosis occurs as part of normal ossification and fusion and may, at times cause pain.
Occasionally, this pain may be significant and be associated with edema of the bone and surrounding soft-tissues (synchondritis). Where pain is lateralized to an abnormal synchondrosis, consider MRI.
It may also be associated with infection. Where pain is associated with synchondritis and raised inflammatory markers or constitutional symptoms, e.g. temperature, think infection.
Sometimes, non-infectious causes may present similarly, e.g. CNO/CRMO.
In this case, inflammatory markers were normal and symptoms settled with rest and he was asymptomatic and back to running around normally at 3 month follow up.
