A 13-year old intact female poodle showed persistent signs of estrus. Ultrasonographically, a large cystic mass containing echogenic fluid with a thin wall was observed, and it was 8 cm in diameter. The cystic mass was located at the mesovarium between the left ovary and uterine horn, and it was identified as a giant parovarian cyst. A right ovarian mass was histologically diagnosed as a granulosa cell tumor. Persistent estrogen hormone secretion by the granulosa cell tumor was thought to cause a rapid increase in the size of the parovarian cyst. This rare cystic mass originated from the genital system and was differentiated from the uterus.
一只13岁未绝育的雌性贵宾犬表现出持续的发情迹象。超声检查发现一个大的囊性肿物，内含回声性液体，壁薄，直径8厘米。该囊性肿物位于左卵巢和子宫角之间的卵巢系膜处，被确定为巨大的卵巢冠囊肿。右侧卵巢肿物经组织学诊断为颗粒细胞瘤。认为颗粒细胞瘤持续分泌雌激素导致卵巢冠囊肿迅速增大。这个罕见的囊性肿物起源于生殖系统，与子宫相鉴别。
