Unsual giant cyst as a consequence of the ovarian remnant syndrome in a bitch

The canine ovary is a common place for the development of cystic structures with an incidence of80% of all canine ovaries diseases (Dow, 1960). In the bitch, the cystic pathology of the ovary includes ovarian, epithelial and stromal cysts, and paraovaric cysts (McEntee et al., 1990). Those cysts are stromal, classically distinct in follicular and luteinic. Parovarian cysts originating from remnants of mesonephric or paramesonephric tubules and ducts can also occur adjacent to the ovaries (Johnston et al. 2001 ).
