Plain-English summary
A 5-year-old male Miniature Schnauzer was brought to the vet because he had signs of feminization and one undescended testicle. Imaging tests showed an enlarged testis and a fluid-filled cavity resembling a uterus, which is unusual for a male dog. The vet performed surgery to remove the abnormal structures, confirming the diagnosis of persistent Mullerian duct syndrome (a condition where male dogs have female reproductive organs) and found a Sertoli cell tumor in the testis. After surgery, the dog was treated and showed improvement.

Abstract
A 5-year-old male Miniature Schnauzer was presented with unilateral cryptorchidism and signs of feminization. Abdominal ultrasonography revealed an enlarged right testis and a large, fluid-filled cavity that appeared to arise from the prostate. Computed tomography revealed the cavity to be consistent with an enlarged uterine body, arising from the prostate, and showed two structures resembling uterine horns that terminated close to the adjacent testes. The dog had a normal male karyotype, 78 XY. Gonadohysterectomy was performed and both the surgical and the histological findings confirmed the presence of a uterus in this male animal, resulting in a diagnosis of persistent Mullerian duct syndrome (PMDS). The enlarged intra-abdominal testis contained a Sertoli cell tumour. Computed tomography proved to be an excellent diagnostic tool for PMDS.
