Enlargement of the left ischiopubic synchondrosis with small lytic areas, and irregular edges.

Case Discussion

CT appearances of left ischiopubic synchondrosis asymmetry.

The ischiopubic synchondrosis may show an increase in radiotracer uptake on radionuclide bone imaging. It represents a normal phase of skeletal development that may mimic a bone lesion on x-rays and radionuclide bone scans.
