Fasciitis with overlying skin involvement in a 56-year-old man 37 months after allogeneic hematopoietic stem cell transplantation for multiple myeloma (patient 5 in Table 1 and Table 2). A, Erythema and induration on the anterolateral aspect of the right thigh. B, Axial T1-weighted spin-echo image demonstrates thickening of the skin, with intervening fat dropout (arrowheads) overlying a region of narrowing and sclerosis of the subcutis. There is also thickening of the adjacent superficial fascia (arrow). C, Axial 3-dimensional gradient recalled echo image after administration of contrast medium demonstrates mild enhancement of the skin and subcutis in the region of sclerosis, with more prominent and extensive enhancement along the deep fascia (arrows). Magnetic resonance imaging total score of 8 (score of 2 each for skin, septa, deep fascia, and epimysium).
