T2-weighted (A) sagittal and (B) transverse MR images of a 6-year old Border collie with a C4-C5 HNPE. The intervertebral disc space is narrowed and contains a reduced volume of hyperintense nucleus pulposus. There is a ventral extradural homogenously hyperintense compressive lesion. (B) The compressive material is midline and has a bilobed, “seagull” appearance. T2-weighted (C) sagittal and (D) transverse images of 7-year old Beagle with acute onset paraplegia. Although HNPE occurs most often in the cervical region, this dog was diagnosed with an L2-L3 HNPE.
