Abstract:
A 4-year-old chicken was presented with a history of anorexia, depression, and blindness. An ultrasound examination of the coelomic cavity was performed that revealed splenomegaly, hepatic nodules, and hypoechoic thickening of the intestinal wall. Ultrasonography of the coelomic cavity was done and revealed splenomegaly, nodular hepatic changes, and hypoechoic thickening of the intestinal wall. A diagnosis of Marek's disease was made based on the history and extension of the abdominal organ changes and confirmed by histopathology. This study describes an ultrasonographic appearance of Marek's disease in a chicken and emphasizes the importance and benefits of ultrasonography in staging the progression of Marek's disease.
