A 9-month old, female, stray dog was rescued and conducted to a university veterinary hospital. Moderate anemia was observed and abdominal ultrasound revealed pancreatitis. Right kidney was not visualized due to intestinal gas. Urinalysis was normal. Castration was performed three weeks later. Before discharge, abdominal ultrasound was performed for internal sutures examination. A cyst-like structure was present in the right retroperitoneal space with what appeared to be tubular worms inside it, not observed in previous evaluation. An ectopic dioctophymosis diagnosis was made. Two female Dioctophyme renale were surgically removed from the structure. Right kidney was hyperemic but not removed. No sign of peritonitis was observed. The dog recovered well. Laboratory follow-up showed no abnormalities a year after the episode and Doppler ultrasound revealed a mild right nephropathy. This is the first canine ectopic dioctophymosis case with only an abdominal cyst-like structure containing viable nematodes, successfully treated. It represents the rarity and difficulties in diagnosing ectopic dioctophymosis even in enzootic locations, highlighting the importance of ultrasonographic screening for such silent, potentially zoonotic disease.
一只 9 个月大的雌性流浪犬被救助并送往一所大学兽医医院。检查发现中度贫血，腹部超声显示胰腺炎。由于肠气，右肾无法显示。尿液分析正常。三周后进行了去势手术。在出院前，对腹部超声进行了内部缝线检查。在右腹膜后间隙发现一个囊肿样结构，内部似乎有管状蠕虫，但在之前的评估中没有观察到。诊断为异位双腔吸虫病。从结构中成功切除了两条雌性双腔吸虫。右肾充血但未切除。未观察到腹膜炎迹象。狗恢复良好。一年后实验室随访未发现异常，多普勒超声显示右肾功能轻度减退。这是首例仅表现为含有存活线虫的腹部囊肿样结构的犬异位双腔吸虫病病例，得到了成功治疗。这表明即使在流行地区，异位双腔吸虫病的诊断也非常罕见且困难，突出了超声筛查这种隐匿性、潜在人畜共患病的重要性。
