Abstract

The incidence of testicular pathologies are common among cryptorchid dogs. A ten-year-old bilaterally cryptorchid male Labrador retriever was presented with a large mass below the right caudal abdomen parallel to the prepuce. The mass had progressively enlarged in size over the past few weeks. On abdominal ultrasound, the mass measured 6.89 cm × 8.22 cm and appeared mixed in echogenicity with multifocal anechoic areas and well-defined borders. The retained left testicle could be located anterior to the left inguinal canal subcutaneously. Based on the history, physical examination and ultrasonographical examination findings, a tentative diagnosis of the mass being of testicular origin was made. The affected and retained testes were surgically removed under general anesthesia. The histopathological examination confirmed the testicular pathology as testicular cystic fibrosis, which was an unusual finding.
