Type II metastasis in the right paravertebral musculature in a patient with lung carcinoma. (a) On CT, the lesion (arrow) shows central low attenuation and rim enhancement. (b) On the T1w image (T1w flash 2D, TR/TE: 142/2.2 ms) the lesion (arrow) is isointense in comparison to the unaffected musculature. (c) On T2w image (half-Fourier acquisition turbo spin echo pulse sequence, HASTE, TR/TE: 800/120 ms) the lesion is isointense (arrow). (d) On MRI after administration of contrast medium (T1w flash 2D image with fat saturation, TR/TE: 209/2.3 ms) the lesion shows central low attenuation and rim enhancement (arrow).
