Abscess of bovine brain stem diagnosed by contrast MRI examinations.
A 3-month-old, female Japanese Black calf that showed signs of neurological dysfunction soon after birth was twice examined by magnetic resonance imaging (MRI). Survey MR images showed changes in a hydrocephalus from mild to severe and the existence of a mass above the brain stem that could be distinguished from the surrounding cerebral parenchyma. Contrast MRI examinations using Gd-DO3A-butriol showed the mass to have a doughnut-like form. As the mass changed, the clinical signs aggravated. We diagnosed a brain stem abscess, which we confirmed pathologically. To our knowledge there are no other reports of the use of contrast MRI to examine cattle.
