case_images: (a) Low T12 signal on lumbar T1-weighted MRI (red circle) and (b) punched-out lesion in the skull on a cranial radiograph were observed (red circles).. MRI: magnetic resonance imaging.

case_images: Low signal intensity at T12 on lumbar T1-weighted magnetic resonance imaging (MRI) and a punched-out lesion in the skull on a cranial radiograph were observed (Figure 1).

case_images: (a) Low L1 signal on lumbar T1-weighted MRI and (b) punched-out lesion in the skull on cranial radiograph were observed (red circles). (c) Punched-out lesions in the transverse process and ilium on 3D CT of the lumbopelvic region were also recognized (red circles).. CT: computed tomography; MRI: magnetic resonance imaging.

case_images: IgG level (6481 mg/dL), and a high beta2-microglobulin level (4.13 mg/dL) were observed, again as for Case 1. In addition, low signal intensity at L1 on T1-weighted MRI and punched-out lesions in the skull radiography and in the transverse process and ilium on 3D computed tomography (CT) of the lumbopelvic region were recognized (Figure 2).
