Original publication title: IMAGING DIAGNOSIS-MAGNETIC RESONANCE IMAGING OF DIFFUSE LEPTOMENINGEAL OLIGODENDROGLIOMATOSIS IN A DOG WITH "DURAL TAIL SIGN".

Plain-English summary
A 7.5-year-old male neutered Staffordshire bull terrier was brought in for weakness in all four legs (tetraparesis) and seizures that had been going on for a while. An MRI showed unusual brain and spinal cord lesions, which were diagnosed as diffuse leptomeningeal oligodendrogliomatosis, a type of brain tumor. This case is notable because it presented with a unique MRI feature called the "dural tail sign," which hasn't been reported in dogs before. Unfortunately, the prognosis for this condition can be poor, and treatment options may be limited.

Abstract
A case of diffuse leptomeningeal oligodendrogliomatosis affecting the brain and spinal cord of a dog is presented. A 7.5-year old, male neutered Staffordshire bull terrier presented for evaluation of a chronic history of tetraparesis and seizures, with a multifocal neuroanatomical localization was determined. Extra-axial intradural lesions with an atypical presentation of a dural tail sign were seen on MRI. Histologically, the lesions were consistent with leptomeningeal oligodendrogliomatosis. To the authors' knowledge, a dural tail sign has not previously been reported as an MRI characteristic of diffuse leptomeningeal oligodendrogliomatosis in dogs.
