Presentation transcript:

Acute osteopenic compression fracture of the L1 vertebral body simulating metastasis. Acute osteopenic compression fracture of the L1 vertebral body simulating metastasis. The mean ADC value of the lesion is 2.8 × 10−4 mm2/s.A, Sagittal T1-weighted MR image (600/8; section thickness, 5 mm; intersection spacing, 1 mm; FOV, 32 cm; matrix, 512 × 512) shows the lesion as diffusely hypointense (arrow). Typical appearance of benign compression fracture involves the T12 vertebral body, with a bandlike area of abnormal signal intensity (arrowhead).B, Sagittal T2-weighted fat-suppressed MR image (3000/99; section thickness, 5 mm; intersection spacing, 1 mm; FOV, 32 cm) shows the lesion as hyperintense (arrow). Typical appearance of benign compression fracture involves the T12 vertebral body, with a bandlike area of abnormal signal intensity (arrowhead).C, Sagittal contrast-enhanced T1-weighted fat-suppressed MR image (416/8.3; section thickness, 5 mm; intersection spacing, 1 mm; FOV, 32 cm) shows the lesion as enhanced (arrow). Typical appearance of benign compression fracture involves the T12 vertebral body, with horizontal bandlike enhancement paralleling the endplate (arrowhead).D, Sagittal diffusion-weighted MR image (5000/96.4; bandwidth, 125 kHz; FOV, 32 cm; matrix, 128 × 128; section thickness, 5 mm; intersection spacing, 1 mm) shows the lesion as hyperintense (arrow). Benign compression fracture is mildly hyperintense (arrowhead). Xiaohong Joe Zhou et al. AJNR Am J Neuroradiol 2002;23:165-170 ©2002 by American Society of Neuroradiology
