1 Metastatic melanoma in a 56-year-old man
Metastatic melanoma in a 56-year-old man.A and B, Routine T1- and T2-weighted images of metastatic melanoma with pathologic fracture of L2 (arrows). Metastatic melanoma in a 56-year-old man.A and B, Routine T1- and T2-weighted images of metastatic melanoma with pathologic fracture of L2 (arrows). Metastatic lesions of L1 and L3 are difficult to see on the routine sequences.C, In-phase image (TE = 4.6 ms).D, Opposed-phase image (echo time [TE] = 2.4 ms). Marrow replaced by tumor does not suppress (arrows), whereas the normal fatty marrow appears dark on these images (asterisks).E, In-phase image with region of interest cursor in place. Signal intensity ratio of L2 is 0.90, indicating the absence of fat and a malignant result.F, Opposed-phase image with region of interest cursor in place. Signal intensity ratio of L2 is 0.90, indicating the absence of fat and a malignant result. W.K. Erly et al. AJNR Am J Neuroradiol 2006;27: ©2006 by American Society of Neuroradiology
