A 34-year-old Caucasian female presented during the third trimester of her pregnancy with bilateral hip pain that became progressively severe. Imaging of her pelvis and bilateral hips with MRI obtained during her third trimester of pregnancy demonstrated bilateral bone-marrow edema of the femoral heads and the sacrum at S1. Repeat MRI performed at 6 months postpartum revealed resolution of edema. MRI is considered the best diagnostic test for this condition in regards to sensitivity and specificity.
