Hypoplasia of the adenohypophysis in a Sprague-Dawley rat.
Pathological examination performed on a male 70-day-old Sprague-Dawley rat revealed formation of a large cyst in the hypophysis. The cyst, which completely occupied the adenohypophyseal area, was lined by the epithelial cells. Small masses of the adenohypophyseal cells were occasionally seen to sprout from the cyst wall epithelium.
