Plain-English summary
A 32-month-old Angus bull was brought in because of a swelling near the base of his scrotum that had been growing for two months. The mass was diagnosed as a penile hematoma, which was causing difficulty with mating. Despite attempts to manage it without surgery, the hematoma continued to grow. Eventually, the bull underwent surgery to remove the hematoma, and after a recovery period of 60 days, he returned to breeding without any issues. The surgery was successful, and he remained healthy and active for two years afterward.

Abstract
A 32-month-old Angus bull was evaluated because of a 2-month history of a slowly progressive swelling located cranial to the base of the scrotum. The mass was 8 x 8 x 6 cm, and was causing phimosis. The mass was determined to be a penile hematoma on the basis of results of ultrasonography and exploratory surgery. Surgical evacuation was not performed initially because the deep fascia of the penis was intact and the hematoma was small; however, the hematoma enlarged slowly during the ensuring 2 months, despite sexual rest and isolation from other livestock. Doppler ultrasonography and positive-contrast corpus cavernosography were performed, and the hematoma was seen as a space-occupying mass within the corpus cavernosum penis; vascular anomalies were not found. The penile hematoma was surgically excised, and the bull was isolated for 60 days. At follow-up, the owner indicated that the bull had returned to pasture-breeding soundness and was still being used 2 years after surgery. The small penile hematoma in this bull was unusual in that it did not respond to medical treatment. Surgical treatment was apparently curative, even though surgery was not performed until 4 months after the hematoma was first detected.
