Plain-English summary
A 12-year-old Thoroughbred stallion was found to have aspermia, which means he was unable to produce sperm, due to a condition called generalized lymphosarcoma, a type of cancer. The cancer cells invaded the epididymis, which is the part of the male reproductive system that stores sperm, leading to swelling and thickening of both epididymides. Fortunately, the testes themselves were not affected by the cancer. The ultrasound images showed a nodular pattern that looked similar to what is seen in cases of infectious epididymitis, which is an infection of the epididymis. The outcome of the treatment for this condition was not specified in the abstract.
Abstract
Aspermia was diagnosed in a 12-year-old Thoroughbred stallion with generalized lymphosarcoma. Invasion of the epididymus by neoplastic cells caused thickening and enlargement of both epididymes. The testes were not affected. The nodular ultrasonographic architecture was similar to that in previously reported cases of infectious epididymitis.
