BACKGROUND AND AIM
Knowledge of normal ultrasonographic dimensions of the liver and associated vascular structures is an important indicator for the diagnosis of hepatic diseases. Enlargement of the liver beyond its normal dimensions is the term of hepatomegaly and ultrasonography is the primary and the suitable diagnostic technique for this condition. Therefore, this study aimed to describe the clinical and ultrasonographic findings of liver diseases causing hepatomegaly in 30 buffaloes as well as to provide a range of liver dimensions and its blood vessel measurements in normal and diseased buffaloes.
MATERIALS AND METHODS
The study population included 30 buffaloes that were admitted to the clinic of the Faculty of Veterinary Medicine - Zagazig University for investigation of clinical signs associated with gastrointestinal diseases such as anorexia, chronic weight loss, and variable degrees of diarrhea or constipation. The animals were subjected to thorough clinical and ultrasonographic investigations. In addition, 10 healthy buffaloes were investigated ultrasonographically and post-slaughtering for comparison of liver dimensions and physical appearance.
RESULTS
Three conditions causing hepatomegaly were identified in this study as multiple focal hepatic lesions, diffuse fatty liver, and hepatic congestion. Clinically, it was difficult to differentiate between each condition while ultrasonography was the ideal tool for diagnosis after comparing with necropsy as a gold standard tool. Hepatomegaly was recorded in all affected animals with a significant decrease in the size of the portal vein (PV) and caudal vena cava (CVC) in animals affected with multiple focal hepatic lesions and fatty liver disease while the size of the PV and CVC was significantly increased in buffaloes with hepatic congestion.
CONCLUSION
Ultrasonography can aid to accurately identify buffaloes with hepatomegaly and differentiate between different lesions involved.
背景与目的
了解肝脏及相关血管结构的正常超声测量值是诊断肝脏疾病的重要指标。肝脏超出正常大小即为肝肿大，超声检查是诊断该病症的主要且适用的诊断技术。因此，本研究旨在描述30头水牛中导致肝肿大的肝脏疾病的临床和超声检查结果，并提供正常和患病水牛的肝脏大小及其血管测量范围。
材料与方法
研究对象包括30头水牛，这些水牛被送至宰加济格大学兽医学院诊所，以调查与胃肠道疾病相关的临床症状，如厌食、慢性体重减轻以及不同程度的腹泻或便秘。对这些动物进行了全面的临床和超声检查。此外，对10头健康水牛进行了超声检查，并在屠宰后对肝脏大小和外观进行了比较。
结果
本研究确定了三种导致肝肿大的病症，即多发性局灶性肝损伤、弥漫性脂肪肝和肝充血。临床上，很难区分每种病症，而超声检查与作为金标准工具的尸检相比，是诊断的理想工具。所有患病动物均出现肝肿大，多发性局灶性肝损伤和脂肪肝病动物的门静脉（PV）和尾腔静脉（CVC）大小显著减小，而肝充血水牛的PV和CVC大小显著增加。
结论
超声检查有助于准确识别肝肿大的水牛，并区分所涉及的不同病变。
