Case 3
Lateral radiographs of the left (a) and right (b) lower extremities (a, b) show prominence of the anterior mid cortex of bilateral tibias without associated periosteal reaction or bone abnormalities (arrows)
Axial T1 (c), fat saturated T2 (d) and post-gadolinium T1 (e) MR images, and sagittal post-gadolinium T1 (f, left; g, right) MR images with the lower extremities were obtained 2.5 months after the aforementioned x-rays. These images show bilateral anterior periosteal thickening, increased T2 signal intensity and enhancement noted within the bone marrow and anterior soft tissues of the mid third of both tibias (arrows), more prominent on the left than on the right
