Overview

Signalment and History

Patient is a 7 yr old, MN, Yorkie with diagnosed with hyperadrenocorticism. A CT scan of the abdomen and pituitary gland was requested to differentiate pituitary vs adrenal dependent hyperadrenocorticism.

Diagnostics Prior to HD CT Scan

  • Normal liver enzymes; triglycerides 1,163
  • ACTH stim: Post > 50
  • LDDS: baseline: 11.6, 4 hrs: 11.6, 8 hrs: 10.1

High-Definition CT Scan

Patient was anesthetized and a pre contrast CT scan of the skull was performed. Afterwards, Omnipaque™ (contrast agent) was administered IV and post-contrast studies of the skull and abdomen were acquired.

Pertinent Findings From Our Board-Certified Radiologist's Report

  • Bilateral symmetrical enlargement of adrenal glands
  • Pituitary Macroadenoma
  • CT Scan is consistent with pituitary dependent hyperadrenocorticism


Following the CT Scan

Medical therapy for hyperadrenocorticism and monitoring for CNS signs were recommended
