Figure 3. A 63-year-old female with relapsing multiple myeloma developed paraparesis following chemotherapy. (a) Fusiform enlargement of the spinal cord (white arrow) with increased T2 signal and diffusion restriction (not shown) were diagnosed 24 h later at MRI. (b) In the same session, MRI of the head disclosed areas of restricted diffusion in both occipital lobes representing acute parenchymal infarction (white arrows). (c) At autopsy, transversal sections through the thoracic spinal cord showed severe tissue softening and defects, especially in the central parts (white arrow). (d) Both lungs showed large areas of haemorrhagic infarction. Note also pulmonary vessel occlusion by fungi responsible for haemorrhagic infarction (white arrow).
