Hyperadrenocorticism is an uncommon but important endocrine disease in guinea pigs, but due to its subtle clinical signs and the limited information in veterinary literature, it can be underdiagnosed or misdiagnosed. Ultrasound of the adrenal glands in patients with suspected hyperadrenocorticism can help in identifying adrenomegaly. The purpose of this prospective study was to identify ultrasonographic adrenal gland dimensions in presumed healthy guinea pigs using the same standardized method described for dogs and cats. A conscious ultrasound scan was conducted on twenty client-owned, presumed healthy guinea pigs, and their adrenal glands were measured. A possible correlation between adrenal dimensions with age, sex, and body weight was investigated. The mean length, cranial and caudal pole thickness for the left and right adrenal glands were, respectively, 12.64 ± 2.11 mm and 11.55 ± 1.52 mm; 4.83 mm ± 1.03 mm and 4.69 ± 1.34 mm; 4.8 ± 1.23 mm and 4.04 ± 0.75 mm. The thickness of the left caudal pole was significantly higher than the right (P = 0.02). A significant positive correlation was found between the length of the left adrenal gland and both age (r = 0.46; P = .03) and weight (r = 0.59; P = .01). Statistical correlation between the thickness of each cranial and caudal pole, with age, sex, or weight, was not found. The dimensions provided could prove a useful tool in the clinical evaluation of guinea pigs with suspected hyperadrenocorticism.
库兴氏综合征是一种罕见但重要的豚鼠内分泌疾病，但由于其临床症状不明显，兽医文献中的信息有限，因此可能会被漏诊或误诊。对疑似库兴氏综合征的患者进行肾上腺超声检查有助于确定肾上腺肿大。本前瞻性研究的目的是使用与犬猫相同的标准化方法确定疑似健康豚鼠的超声肾上腺尺寸。对 20 只来自客户的、疑似健康的豚鼠进行了意识状态下的超声扫描，并对其肾上腺进行了测量。研究了肾上腺尺寸与年龄、性别和体重之间的可能相关性。左右侧肾上腺的平均长度、颅侧和尾侧极厚度分别为 12.64 ± 2.11mm 和 11.55 ± 1.52mm；4.83mm ± 1.03mm 和 4.69 ± 1.34mm；4.8 ± 1.23mm 和 4.04 ± 0.75mm。左侧尾极的厚度明显高于右侧（P=0.02）。还发现左侧肾上腺的长度与年龄（r=0.46；P=0.03）和体重（r=0.59；P=0.01）呈显著正相关。未发现每个颅侧和尾侧极的厚度与年龄、性别或体重之间存在统计学相关性。提供的这些尺寸可能是评估疑似库兴氏综合征豚鼠的有用工具。
