From: Cystic transformation of focal lesions after therapy is associated with remission but adverse outcome in myeloma

Fig. 1

Representative images from a patient with a large focal lesion in the sacrum with extramedullary growth. Images at baseline in the top row with common features of a focal myeloma lesion (red arrows): Decreased signal intensity on T1-weighted images (a) and increased intensity on T2-weighted images (b) as well as DWI (c). PET/CT proved increased FDG uptake at primary diagnosis. Upon achieving remission after ASCT (bottom row), the lesion decreased significantly in size as depicted on T1- (e) and T2-weighted (f) images. The lesion showed a hyperintense signal on T2-weighted images but no increased FDG uptake compared to the surrounding tissue. MRI images in coronar orientation, PET/CT in transversal orientation
