Diagnosing ovarian tumors in dogs can be challenging since the clinical symptoms are often generic. The present case report underscores a rare case in which a suspected unilateral ovarian tumor in a dog was initially identified using ultrasonography and subsequently confirmed to be a luteoma through postoperative histopathology.
An 8-year and 6-month-old female Maltese dog presented with a 10-day history of vulvovaginal bleeding, hematuria, and decreased appetite. Physical examination revealed only vaginal bleeding, with no other abnormalities. Laboratory examinations showed no abnormalities, while abdominal radiography revealed the presence of cystic calculi as the sole abnormality. Abdominal ultrasound revealed an enlarged right ovary with regular contour and echogenicity, featuring unusual cystic components surrounding the right ovarian parenchyma. Furthermore, irregular thickening with multiple cystic lesions was observed in the endometrial wall of the bilateral uterine horns, indicative of cystic endometrial hyperplasia. Ultrasonographic findings suggested unilateral right ovarian disease. During ovariohysterectomy, the right ovary was slightly larger than the left ovary and adhered to the surrounding mesenteric fat layer and right pancreatic parenchyma. Histopathological examination confirmed the diagnosis of luteoma in the right ovary. Three days after surgery, the patient's clinical signs exhibited complete improvement, with the return of normal appetite.
This case report highlights a rare diagnosis of unilateral ovarian luteoma based on mild ultrasonographic abnormalities, which was ultimately confirmed on histopathological examination.
在狗中诊断卵巢肿瘤具有挑战性，因为临床症状通常是一般性的。本病例报告强调了一种罕见情况，一只狗的疑似单侧卵巢肿瘤最初通过超声检查发现，随后通过术后组织病理学检查证实为黄体瘤。
一只 8 岁零 6 个月大的雌性马尔济斯犬出现了 10 天的阴道出血、血尿和食欲减退病史。体格检查仅发现阴道出血，无其他异常。实验室检查无异常，腹部 X 光片仅显示存在囊性结石作为唯一异常。腹部超声显示右侧卵巢增大，轮廓和回声正常，右侧卵巢实质周围有不寻常的囊性成分。此外，在双侧子宫角的子宫内膜壁上观察到不规则增厚和多个囊性病变，提示囊性子宫内膜增生。超声检查结果提示单侧右侧卵巢疾病。在卵巢子宫切除术期间，右侧卵巢比左侧稍大，并与周围肠系膜脂肪层和右侧胰腺实质粘连。组织病理学检查证实右侧卵巢黄体瘤的诊断。手术后 3 天，患者的临床症状完全改善，食欲恢复正常。
本病例报告强调了一种罕见的单侧卵巢黄体瘤的诊断，其依据是轻微的超声异常，最终通过组织病理学检查得到证实。
