Figure 3

MRI gradient eco transverse planes at T9 level show an intramedullary round focal signal void in the dorsal funiculus (arrow in (a)) characteristic of haemorrhage and a dorsolateral hypointense rim at T12 level (arrows in (b)) compatible with subdural haematoma, with hemosiderin creating the magnetic susceptibility variation depicted on this sequence.
