Renal hydatid cyst, an uncommon manifestation of infection, presents a diagnostic challenge due to its asymptomatic nature. Here, we report the case of a 34-year-old male who presented with intermittent left flank pain, abdominal fullness, and passage of whitish clots in urine. Physical examination revealed a palpable 15 cm × 11 cm hard mass extending from the left hypochondrium to the left lumbar region. Ultrasonography and contrast-enhanced computed tomography identified a 15 cm Bosniak type 3 complex cystic lesion arising from the left kidney, causing hydronephrosis and hydroureter. The patient underwent a left nephrectomy, and a histopathological examination confirmed a renal hydatid cyst. This case highlights the diagnostic difficulty in differentiating renal hydatid cysts from other renal lesions. Despite suggestive radiological findings, conclusive diagnosis remains elusive, particularly in solitary complex renal cysts. Awareness of renal hydatid cysts in the differential diagnosis is crucial for appropriate management.
肾包虫囊肿是一种罕见的感染表现，因其无症状的特性而带来诊断挑战。在此，我们报告一例34岁男性病例，该患者出现间歇性左腰部疼痛、腹部胀满及尿中排出白色凝块。体格检查发现可触及一个15厘米×11厘米的硬块，从左季肋部延伸至左腰部。超声检查和增强计算机断层扫描发现左肾出现一个15厘米的博斯尼亚克3型复杂性囊性病变，导致肾积水和输尿管积水。患者接受了左肾切除术，组织病理学检查证实为肾包虫囊肿。该病例凸显了鉴别肾包虫囊肿与其他肾脏病变时的诊断困难。尽管有提示性的影像学表现，但确诊仍然困难，尤其是在孤立性复杂性肾囊肿中。在鉴别诊断中认识到肾包虫囊肿对于恰当的处理至关重要。
