Adrenal computed tomography characteristics (aCTc) in healthy cats are known, but reference intervals for diseased cats are lacking. aCTc of cats without evidence of adrenal disease (NAD group) were compared to parameters of cats with possible concurrent adrenal disease (PAD group). The PAD group was assessed for adrenal masses or other morphological deviations using the NAD group as reference. Associations of aCTc with patient variables were explored, and all results were compared with published aCTc of healthy cats. No incidental adrenal masses were identified in the PAD group (n = 92), and only few aCTc differed compared to the NAD group (n = 30). The NAD group showed similar associations of patient variables and aCTc as length (right: 11.5 ± 2.2 mm, left: 11.8 ± 1.7 mm), width (right: 6.4 ± 1.2 mm, left: 5.4 ± 0.8 mm), height (right: 4.5 ± 0.9 mm, left: 4.5 ± 0.8 mm), attenuation (right: 33.1 ± 5.0 Hounsfield units, left: 32.5 ± 5.3 Hounsfield units) and position, but markedly more mineralization (right: 10%, left: 13.3%) than reported in healthy cats. This study provides references of aCTc for diseased cats without evidence of adrenal disease. The result suggests that adrenal incidentalomas seem to be rare in cats.
健康猫的肾上腺计算机断层扫描特征（aCTc）是已知的，但患病猫的参考区间却缺乏。本研究将无肾上腺疾病证据的猫（NAD 组）的 aCTc 与可能同时患有肾上腺疾病的猫（PAD 组）的参数进行了比较。使用 NAD 组作为参考，对 PAD 组的猫进行了肾上腺肿块或其他形态学偏差的评估。探讨了 aCTc 与患者变量的相关性，所有结果均与已发表的健康猫的 aCTc 进行了比较。在 PAD 组（n = 92）中未发现偶发性肾上腺肿块，与 NAD 组（n = 30）相比，只有少数 aCTc 存在差异。NAD 组的患者变量和 aCTc 之间的相关性与长度（右侧：11.5 ± 2.2 毫米，左侧：11.8 ± 1.7 毫米）、宽度（右侧：6.4 ± 1.2 毫米，左侧：5.4 ± 0.8 毫米）、高度（右侧：4.5 ± 0.9 毫米，左侧：4.5 ± 0.8 毫米）、衰减（右侧：33.1 ± 5.0 亨氏单位，左侧：32.5 ± 5.3 亨氏单位）和位置相似，但矿物质化程度明显更高（右侧：10%，左侧：13.3%），与健康猫报道的结果不同。本研究为无肾上腺疾病证据的患病猫提供了 aCTc 的参考。结果表明，猫的偶发性肾上腺肿瘤似乎很少见。
