Non-functional pituitary chromophobe adenoma in a calf.
A 5-month-old male calf showed neurological signs, including circling, in-co-ordination, depression, blindness and eventual recumbency. On necropsy, a mass measuring 3.5 x 4.5 x 5 cm was found at the base of the brain, at the level of the pituitary gland. The hypothalamus and optic nerves were compressed by the dorsally expanding mass. Non-functional pituitary chromophobe adenoma was diagnosed from histochemical, immunohistochemical and electron microscopical findings.
