This study describes the clinical and ultrasonographic features of superficial swellings in dromedary camels (Camelus dromedarius) and evaluates the role of ultrasonography (US) in diagnosing and surgical planning or making treatment decisions for such swellings. One hundred and twenty-three camels of both sexes were included in this study based on the clinical and US evidence of superficial swellings varying in type, stage, content, and site. Clinical and US evaluation of these superficial swellings resulted in diagnoses of abscess (30.08%), hernia (26.83%), cyst (16.26%), tumor (13.01%), hematoma (6.50%), bursitis (3.25%), aneurysm (2.44%), and grade III muscle strain (1.63%). US yielded a higher sensitivity (91-100%) and specificity (97-100%) than clinical examination (75-91%) in differentiating the superficial swellings. The highest specificity value for US in evaluating the swellings was 100% for hernias, cysts, and tumors, while the lowest specificity values were recorded for hematomas (97%), followed by aneurysms (98%). In conclusion, US is a reliable and accurate tool providing rapid differential diagnosis, thus enabling treatment options for different superficial swellings in camels when clinical examinations are inconclusive.
本研究描述了单峰驼（Camelus dromedarius）浅表肿胀的临床和超声特征，并评估了超声（US）在诊断和手术规划或治疗此类肿胀方面的作用。根据浅表肿胀的类型、阶段、内容和部位的临床和 US 证据，本研究纳入了 123 匹雌雄骆驼。对这些浅表肿胀的临床和 US 评估得出的诊断结果为脓肿（30.08%）、疝（26.83%）、囊肿（16.26%）、肿瘤（13.01%）、血肿（6.50%）、滑囊炎（3.25%）、动脉瘤（2.44%）和 III 级肌肉拉伤（1.63%）。US 在区分浅表肿胀方面的敏感性（91-100%）和特异性（97-100%）均高于临床检查（75-91%）。US 对评估肿胀的特异性最高值为疝、囊肿和肿瘤，均为 100%，而血肿的特异性最低值为 97%，其次是动脉瘤，为 98%。总之，US 是一种可靠且准确的工具，可提供快速的鉴别诊断，从而在临床检查不确定时为骆驼的不同浅表肿胀提供治疗选择。
