was changed:
The piglet sign is seen in central pontine myelinolysis. It refers to the appearance of the upper pons in axial T2 and FLAIR images. If theThe areas of demyelination coalescecoalescent T2 signal increase are reminiscent of a pigs snout, with other features on axial MR images resembleresembling the rest of the face of a piglet with the temporal lobes representing ears, the carotid arteries representing the eyes,represent the area of central pontine myelinosis representing snouteyes and the fourth ventricle as the mouth 1,2.
The area of abnormal T2 signal increase is perhaps better known as the trident sign.
