Case Study: Chronic Recurrent Multifocal Osteomyelitis in the Femoral Diaphysis of a Young Female
Figure 4
Axial (a-b) MRI through the right thigh with coronal (c-d) MRI images through both thighs. Displayed axial images are from the level of the white lines in (c) and (d). Sequences are as follows: (a) axial T2 fat saturated (FS) (TE 93 ms. TR 5670 ms.), (b) axial T1FS with gadolinium (TE 17 ms. TE 730 ms.), (c) coronal T1 (TE 14 ms. TR 543 ms.), and (d) coronal T1FS with gadolinium (TE 14 ms. TR 460 ms.). The axial T2 FS image displays the edematous high signal in the medullary space, patchy high signal cortical lesions (black arrows), cortical thickening and periosteal reaction (thick grey arrows), and subtle surrounding soft tissue edema (thin grey arrows). Coronal T1 (c) shows the low signal within the medullary space, a characteristic feature of involvement. After gadolinium (b,d) there is intense enhancement of the marrow, periosteum (thick grey arrows), with some enhancement also seen in the bordering musculature (thin grey arrows).
