Astrocytoma in a boar.

A 2-year-old Duroc boar was examined because of weakness, ataxia, and blindness. During hospitalization, fever spikes of about 41.6 C (107 F) were recorded every 24 hours. The tentative diagnosis was a space occupying mass in the diencephalon. The boar's condition deteriorated rapidly, so the boar was euthanatized and necropsied. On the basis of gross and histopathologic findings, as well as cell marker-specific-staining characteristics, astrocytoma was diagnosed.
