Necrotizing encephalitis in a Maltese dog in Belgium.

A one-year-old male-Maltese dog suffered seizures, blindness and behaviour change. The brain CT Scan examination evidenced an asymmetric ventricular e nlargement, hypodensities and pathological contrast enhancements. A presump tive diagnosis of necrotizing encephalitis was made. Histopathology demonst rated lesions similar to those published in Maltese dogs, Yorkshire Terrier s and Pug dogs with necrotizing encephalitis, i.e, perivascular and meninge al mononuclear cell accumulation, focal microgliosis, astrocytosis, mononuc lear cell infiltration with spongiosis, necrosis and cavitation. The presen t case is, to the author's knowledge, the first report of necrotizing encep halitis in a Maltese dog outside the USA.
