Presumptive Haematomyelia Secondary to Warfarin Toxicosis in a Dog

Figure 2

MRI transverse planes at T8 level (a, b). The images show an intramedullary lesion which is hyper- to isointense with and hypointense rim on T1-weighted images (a) and hypointense with a hyperintense rim on T2-weighted images (b). This pattern is suggestive of early subacute haematoma surrounded by fluid. At T12 level (c, d), the images show an intramedullary lesion which is mildly hyperintense on T1-weighted images (c) and hyperintense on T2 (d). These findings are suggestive of late subacute haematoma.
