- PITUITARY ABSCESS WITH SPREAD INTO THE THIRD VENTRICLE
- University of Pennsylvania
- Close examination of this slide reveals an abscess arising in the hypophysis (the pituitary is actually absent in this image.) Pituitary abscesses in cattle may result from ascending bacterial infection of the sinuses, middle ear, or may arise from extension of bacterial infectious from the practice of implanting rings in the nose of bulls, through the venous plexus of the nose and dorsal roof of the sinuses, into the rete mirabile, which surrounds the pituitary gland. The sectioning of the brain is assymmetrical in this image.
