From: MRI in multiple myeloma: a pictorial review of diagnostic and post-treatment findings
T1-weighted (top) and T2-weighted STIR (bottom) images of newly diagnosed myeloma patient a with diffuse infiltration of the bone marrow and a large focal lesion in the right intertrochanteric region (arrows). Five years after receiving systemic therapy and local irradiation on the right intertrochanteric region b there is an increase in signal intensity in the centre of the focal lesion on STIR images compatible with necrosis. Also remark the broad fatty halo surrounding the lesion. Both of these imaging findings indicate good response to therapy
