Bilateral hydrosalpinx and cystic endometrial hyperplasia in doe: a case report



CASE HISTORY: Hydrosalpinx is characterized by the accumulation of thin mucus within the lumen of the oviduct and it is rare in small ruminants. A 5-year-old, horned, mixed breed doe with a history of infertility was necropsied for teaching purposes. CLINICAL PRESENTATIONS: Pre-slaughter examination revealed mucopurulent keratoconjunctivitis, rhinitis, synovitis and mastitis with watery purulent discharge from the mammary glands indicated mycoplasmal infection (agalactia). At necropsy, the carcass was congested. The proximal portions of oviducts (Ampula) were distended, thin-walled and fluctuating in palpation. They were filled with clear thin mucus and were conic shaped, with 12 cm in length and 1.3 cm in width at the base and 0.5 cm at the top. The distal part of oviducts (Isthmus) was filled with semisolid purulent discharge causing total tube obstruction. The wall of the uterus and the uterine horns were thickened and mucosa was hyperplastic in appearance with small cysts which were measured at 0.3-0.5 cm. There was a slight fibrous adhesion between the mesosalpinx and the ovaries. The right ovary contained a corpus luteum, a large graafian follicle and numerous corpora albicans. Microscopically, atrophy of the wall of ampula, chronic inflammation of the isthmus and cystic endometrial hyperplasia was seen. DIAGNOSTIC TESTING: Direct examinations and culture of the exudate showed mucus without any secondary infection. ASSESSMENT: On the basis of macroscopic characteristics and laboratory findings, the condition was diagnosed as a bilateral hydrosalpinx due to obstruction of the distal part of the oviducts along with cystic endometrial hyperplasia.
