Renal cysts are generally classified as simple or complex and are further characterised under the Bosniak classification system. Most simple cysts are benign, asymptomatic and discovered incidentally. However, over time, these simple cysts can enlarge, become symptomatic and develop complications, requiring intervention. We present a case of a 70-year-old man with multiple comorbidities who presented with left lower quadrant abdominal pain and haematuria. An abdominal CT scan revealed a large, 26 cm exophytic cyst with high attenuation areas, septations and haemorrhage. Given the patient's tenuous condition and poor functional status, an interventional radiology-guided renal cyst aspiration was performed, resulting in successful reduction of size and symptom resolution. A follow-up ultrasound at 6 months showed no evidence of recurrence. Primary care providers should be aware of the prevalence of renal cysts and their complications, especially haemorrhage, particularly in high risk and elderly patients on anticoagulation or antiplatelet therapy.
肾囊肿通常分为单纯性和复杂性，并根据博斯尼亚克分类系统进一步分类。大多数单纯性囊肿是良性的，无症状，多为偶然发现。然而，随着时间的推移，这些单纯性囊肿可能会增大，出现症状并引发并发症，需要进行干预。我们报告一例70岁男性患者，有多种合并症，表现为左下腹疼痛和血尿。腹部CT扫描显示一个大的、26厘米的外生性囊肿，伴有高密度区、分隔和出血。鉴于患者病情不稳定且功能状态较差，进行了介入放射学引导下的肾囊肿穿刺抽吸术，囊肿大小成功缩小，症状缓解。6个月后的随访超声检查未发现复发迹象。基层医疗服务提供者应了解肾囊肿及其并发症的发生率，尤其是出血，特别是在接受抗凝或抗血小板治疗的高危和老年患者中。
