A 5-year-old, male Yorkshire terrier dog was presented with progressive seizure and anorexia. Definitive diagnosis of necrotizing meningoencephalitis(NME) was made based on characteristic clinical features, brain lesion with MRI, and histopathologic examination. The dog was treated with prednisolone for 20 days, firstly. Prednisolone and mycophenolate mofetil(MMF) were then administered for 40 days following the initial therapy. However, the clinical signs were not improved and seizure frequency was increased. This patient survived around 2 months after diagnosis. This case report described the clinical findings, imaging characteristics and pathologic features of NME in a Yorkshire terrier with trial treatment using MMF.

A Jindo dog (8-month-old, intact male) was referred for hind limb lameness on the right side. The dog was diagnosed with a simple femoral fracture by radiological examination. After surgical fixation of the femoral fracture, tramadol: a narcotic-like synthetic analgesic was intravenously administrated for post-operative analgesia. After injection of the tramadol, generalized tonic clonic seizure was immediately occurred in the dog. Seventeen hours later, the dog died despite intensive care. We suspected that tramadol might induce the seizurogenic effect resulted in death. A necropsy was performed to examine the cause of the death. In consequence, the dog was diagnosed as necrotizing meningoencephalitis (NME) based on histopathological examination. We would be concerned that tramadol may be related to seizure activity in the NME patient. From this case, it is known that although tramadol has been proven to be a safe and effective agent for the control of pain in veterinary medicine, it would be carefully used to patient with history of neurological diseases including meningoencephalitis, hydrocephalus, and encephalopathy.

Computed tomography revealed hypodense areas in the brain and ventriculomegaly, Multifocal lesions were noted in magnetic resonance images, which were hypointense in T1-weighted images and hyperintense in T2-weighted images. Ventriculomegaly and intracranial arachnoid cyst were also observed. Finally, it was diagnosed as necrotizing meningoencephalitis by histopathologic examination after necropsy.
