目的:分析1例成人肾血管平滑肌腺样瘤的临床表现、影像学和病理学特点,以探讨其诊疗方式及预后。方法:回顾性分析我院2014年8月收治的1例成人肾血管平滑肌腺样瘤患者的临床资料:患者无腰痛、肉眼血尿等特异性临床表现,腹部彩超示左肾下极可见6.3cm×4.9cm液性暗区,双肾平扫CT提示左肾下极有6.0cm类圆形低密度影,边界清,双肾强化CT实质期和排泄期均未见明显强化。术前初步诊断为左肾囊肿,行后腹腔镜下左肾囊肿去顶减压术。结果:术后病理检查诊断为肾血管平滑肌腺样瘤。随访3个月,肿瘤无复发和转移。结论:肾血管平滑肌腺样瘤极其罕见,确诊仅能依靠病理检查;临床上易于其他肾脏良恶性肿瘤混淆;手术切除是目前最为有效的治疗方式,预后较好。
Objective: To analyze the clinical manifestations, imaging features and pathological features of 1 adult renal vascular smooth muscle adenomatosis in order to explore its diagnosis and treatment. Methods: A retrospective analysis of our hospital in August 2014 admitted to a case of adult patients with renal vascular smooth muscle adenocarcinoma clinical data: patients with low back pain, gross hematuria and other specific clinical manifestations of the abdominal ultrasonography showed the left renal can be seen 6.3cm × 4.9cm liquid dark area, bilateral renal plain CT showed that the left renal subclavian 6.0cm class round low density, clear boundary, double renal enhancement CT substantive and excretory period were not significantly enhanced. Preoperative diagnosis of left renal cysts, retroperitoneal laparoscopic left renal cyst decompression surgery. Results: Postoperative pathological diagnosis of renal vascular smooth muscle adenoid. Follow-up 3 months, no recurrence and metastasis of the tumor. Conclusions: Renal vascular smooth muscle adenomatosis is extremely rare. Diagnosis can only rely on pathological examination. It is easily confused with benign and malignant tumors of other neoplasms. Surgical resection is the most effective treatment and the prognosis is good.
