Ultrasonographic features of some visceral organs of the Philippine brown deer, Rusa marianna (Desmarest, 1822) (Cetartiodactyla: Cervidae)

Abstract

The study was conducted to determine the ultrasonographic features and measurements of the liver, spleen, kidney, stomach and urinary bladder of the Philippine brown deer (Rusa marianna). Eight deer were examined using an ultrasound machine equipped with a 5.0 MHz micro-convex scanner. Variations on the ultrasound features and measurements between sex and age were determined. Echo mean values of the liver and spleen were also obtained. The parenchyma of the liver and spleen was homogenously anechoic to hypoechoic. The liver capsule was seen as hypoechoic to hyperechoic while the splenic capsule was hyperechoic. The liver and spleen parenchyma of the adults have higher echo mean values than in juveniles (P<0.05). The renal pelvis and capsule appeared as hyperechoic, whereas the renal medulla was anechoic while the cortex was anechoic to hypoechoic. The walls of the different chambers of the stomach were seen as a hyperechoic line. The adult deer have thicker ruminal wall than juveniles (P<0.05). The urinary bladder was seen as hyperechoic with an anechoic lumen. The results of the study can be used as a reference for the diagnosis of diseases and disorders of the liver, spleen, kidney, stomach and urinary bladder in Philippine brown deer.
