The First “Volunteer” Normal Thoracolumbar Spine
The First Clinical Patient • 7-year-old MC Weimaraner • One year long history of bilateral hind limb weakness that had progressively worsened • Recent onset seizures • Plan: MRI brain +/- MRI lumbar spine
The First Clinical Patient • Neurologists eagerly awaiting results of the first scan
The First Clinical Patient Intracranial contrast-enhancing mass Presumptive diagnosis: Cystic meningioma
Other Patients • 1-year-old M Mastiff • Wobbly in hind limbs since birth, progressive • Hind limb paresis except when on prednisone • Plan: MRI thoracolumbar spine

Initial Large Animal Experience • 4 month old Potbellied Pig • Fever (105°F) and rear leg weakness • Plan: MRI lumbar spine
Imaging Diagnosis: Diffusely contrast enhancing areas in epaxial muscles -> Muscle biopsy: Myofiber necrosis and degeneration with secondary inflammation and regeneration Ddx: nutritional (white muscle disease), toxic, neurogenic, infectious or ischemic
