From the case:
Ischiopubic synchondrosis - symptomatic
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/75472/annotated_viewer_json?lang=us"}
The MRI sequences demonstrate enlargement of the left ischiopubic synchondrosis with irregular margins, and associated edema and enhancement of the bone marrow and adjacent external obturator muscles.
Normal MR appearance of both hip, and sacroiliac joints. Note minimal peritoneal effusion.
Case Discussion
The MRI findings are suggestive of a stress reaction within an ischiopubic synchondrosis.
On MR imaging, other conditions should be included in the differential diagnosis: stress fracture, post-traumatic osteolysis, osteomyelitis, and bone tumor.
