Bovine uterine enlargement can be attributed to single or multiple pregnancies in physiological cases, or pyometra, hydrometra, uterine tumors, myometritis or uterine perimetritis in pathological cases. However, clinical differential diagnosis has been complicated, thus proper diagnosis and treatment have been considerably difficult. Six types of uterine enlargement from 26 clinical cases were sequentially monitored using transrectal mobile ultrasonography and their outcomes, after appropriate treatments were investigated. They were 12 cases of pyometra, 4 cases of myometritis, 4 cases of hydrometra, 3 cases of perimetritis and 3 cases of uterine tumors. In the cases involving uterine tumors, all of 3 cases were lymphosarcoma on postmortem examinations. The prognosis of chronic myometritis was usually poor; however, prompt and proper diagnostic treatment based on ultrasonographic findings such as combination treatment with prostaglandin F2α (PGF2α), estradiol benzoate and povidone iodine infusion increased the possibility of pregnancy. This suggests that a mobile ultrasonography may be beneficial for conducting a differential diagnosis of uterine enlargement.
