Which additional imaging modality would you like to obtain next?
Either CT or MRI could be obtained to further characterize the lesion. Often, both modalities can be complementary in the evaluation of bone lesions. In this case, MRI was performed first.
On the zoomed frontal images, the lytic lesion is highlighted in green. On the zoomed lateral images, the periosteal and cortical thickening are highlighted in green (compare with the normal cortex in blue which tapers in thickness from diaphysis to epiphysis.)
