Ultrasonographic evaluation of canine and feline anal sacs is a practical promising modality to identify anal sac disease. However, limited data are available about normal ultrasound morphology of the anal sacs. This study describes the ultrasound morphology of presumed normal anal sacs in a larger sample of client-owned dogs and cats. A single-institutional prospective cross-sectional descriptive study was performed, and 137 dogs and 131 cats were included. The most common ultrasound features of the evaluated anal sacs in the dorsal plane were oval shape (99.3% of dogs and 98.5% of cats) and bilaterally similar content (94.2% of dogs and 95.4% of cats), mostly hypoechoic with diffusely hyperechoic points or unformed echogenic material (42.6% of dogs and 44% of cats). Gas in the lumen of the anal sac was detected in two dogs and mineralization in one dog. There was a statistically significant positive correlation between body weight and the size of anal sacs in dogs ≤15 kg and cats and a correlation between age and the size of anal sacs in cats. This simple method provides additional clinically significant information in detecting abnormal findings in asymptomatic patients and could contribute to the early detection of anal sac disease.
犬猫肛门囊的超声评估是识别肛门囊疾病的一种实用且有前景的方法。然而，关于肛门囊正常超声形态的数据有限。本研究描述了在更大样本的宠物狗和猫中推测正常的肛门囊的超声形态。进行了一项单机构前瞻性横断面描述性研究，纳入了137只狗和131只猫。在背平面评估的肛门囊中，最常见的超声特征是椭圆形（99.3%的狗和98.5%的猫）和双侧内容物相似（94.2%的狗和95.4%的猫），大多为低回声，伴有散在的高回声点或不成形的回声物质（42.6%的狗和44%的猫）。在两只狗的肛门囊腔内检测到气体，在一只狗中检测到矿化。体重与体重≤15 kg的狗及猫的肛门囊大小之间存在统计学上显著的正相关，年龄与猫的肛门囊大小之间存在相关性。这种简单的方法在检测无症状患者的异常发现方面提供了额外的临床重要信息，并有助于肛门囊疾病的早期检测。
