Corpus Callosum Abnormality in a Free-Ranging Coyote (Canis latrans).

A juvenile coyote (Canis latrans) was presented to a wildlife rehabilitation center with intermittent circling, hypernatremia, and elevated blood urea nitrogen. Diagnostic testing supported a diagnosis of hypodipsic hypernatremia. Postmortem magnetic resonance imaging (MRI) and necropsy revealed marked hypoplasia of the corpus callosum, a finding not previously reported in a free-ranging animal.

Assessment of the accuracy of computed tomography for measurement of normal equine pituitary glands.

Objective: To describe the anatomic features of the pituitary gland region in horses via computed tomography (CT) and determine the accuracy of CT for estimating normal equine pituitary gland dimensions.

Animals: 25 adult horses with no clinical signs of pituitary disease.

Procedure: Transverse CT images and gross transverse tissue sections were compared in 2 horses.
