title: Unusual central nervous system lesions in slaughter-weight pigs with porcine circovirus type 2 systemic infection.
abstract: Porcine circovirus type 2 systemic infection was diagnosed in 2 slaughter-weight pigs based on postmortem examination. The infection was associated with unusual central nervous system lesions characterized by a multifocal lymphohistiocytic to granulomatous meningoencephalomyelitis with giant cell formation. The role of these nervous system lesions in the development of the clinical signs in these pigs remains uncertain.
