Four dogs with clinical evidence of hyperadrenocorticism were evaluated by use of x-ray-computed tomography (CT). Adrenal masses were identified accurately and localized. Unilateral adrenal masses were diagnosed accurately in dogs 1, 2, and 3 and were removed surgically via a paracostal retroperitoneal approach to the adrenal gland. Using CT and IV contrast medium, the adrenal mass in dog 3 also was accurately diagnosed as being highly vascular. The histopathologic diagnosis was adrenal adenoma in dogs 1, 2, and 3. In dog 4, the CT-roentgen diagnosis was asymmetric bilateral adrenal enlargement. Necropsy examination of dog 4 indicated moderate enlargement of the left adrenal gland and severe enlargement of the right adrenal gland. Results of microscopic examination indicated chronic inflammation of the left adrenal gland and adenocarcinoma of the right adrenal gland. Use of CT facilitated localization of adrenal masses and fulfilled the needs of a localizing technique. A unilateral mass can be removed surgically via a limited exposure, retroperitoneal incision on the affected side of the animal instead of removal via abdominal laparotomy, which is more invasive. Advantages of CT can reduce the needs of other imaging modalities for the localization of adrenal masses.
对四只具有肾上腺皮质功能亢进临床证据的犬进行了X线计算机断层扫描（CT）评估。准确识别并定位了肾上腺肿块。犬1、2和3被准确诊断为单侧肾上腺肿块，并通过肋旁腹膜后途径对肾上腺进行手术切除。利用CT和静脉造影剂，犬3的肾上腺肿块也被准确诊断为血管丰富。犬1、2和3的组织病理学诊断为肾上腺腺瘤。犬4的CT-X线诊断为双侧肾上腺不对称增大。犬4的尸检显示左肾上腺中度增大，右肾上腺重度增大。显微镜检查结果显示左肾上腺慢性炎症，右肾上腺腺癌。CT的使用有助于肾上腺肿块的定位，并满足了定位技术的需求。单侧肿块可以通过对动物患侧进行有限暴露的腹膜后切口进行手术切除，而不是通过更具侵入性的腹部剖腹术切除。CT的优点是可以减少对其他成像方式进行肾上腺肿块定位的需求。
