Abstract

A juvenile female pig found dead was submitted for necropsy. A focal meningeal red mass measuring 3.5 cm in diameter was located over the left olfactory bulb. Histologically, the mass was composed of polygonal-to-spindle-shaped cells forming vascular clefts with focal invasion of the neuropil of the olfactory bulb. Immunohistochemistry revealed strong expression of vimentin, and a variable labeling of factor VIII-related antigen, smooth muscle actin, and neurotrophin receptor p75. The final diagnosis was a primary meningeal hemangiosarcoma.
