目的:探讨肾周硬化性脂肪肉瘤的临床特点及腹腔镜治疗的安全性。方法:回顾性分析1例经本院收治的肾周硬化性脂肪肉瘤患者的临床资料,探讨其临床特点及其腹腔镜治疗方法。患者年龄72岁,无特征性临床表现。B超发现左侧脾肾间有低回声,大小约8.1cm×4.6cm,内部见血流信号。CT检查提示左肾上极后腹膜内软组织密度影,CT值-11~45HU,增强后不均匀轻度强化,动脉期CT值22~69HU。术前B超引导下行穿刺活检提示为梭形细胞间叶源性肿瘤可能。在全麻下行腹腔镜腹膜后肿物切除术,成功切除病灶,保留肾脏。结果:经病理检查诊断为肾周硬化性脂肪肉瘤。术后随访2个月,未发现肿瘤复发。结论:肾周硬化性脂肪肉瘤临床上少见,多无特征性临床表现,CT检查对协助术前诊断及手术均有重要指导意义。腹腔镜手术治疗肾周硬化性脂肪肉瘤安全有效。
Objective: To investigate the clinical features of perirenal sclerosing liposarcoma and the safety of laparoscopic treatment. Methods: A retrospective analysis of 1 case of perineuronal sclerosing liposarcoma patients admitted to our hospital clinical data, to explore its clinical features and laparoscopic treatment. Patients aged 72 years, no characteristic clinical manifestations. B ultrasound found on the left spleen and kidney have low echo, the size of about 8.1cm × 4.6cm, internal see blood flow signal. CT examination showed that the soft tissue density of the left renal upper pole after intraperitoneal soft tissue, CT value of -11 ~ 45HU, enhanced mild non-uniform enhancement, arterial phase CT value of 22 ~ 69HU. Preoperative B-guided biopsy of the needle tips for the spindle-shaped cell-derived tumors may be. Under general anesthesia laparoscopic retroperitoneal resection, successful removal of the lesion, retain the kidneys. Results: The pathological examination was diagnosed as peritoneal sclerosing liposarcoma. After 2 months of follow-up, no tumor recurrence was found. Conclusion: Peripheral sclerosing liposarcoma is clinically rare and has no clinical manifestations. CT examination is of great guiding significance in assisting preoperative diagnosis and operation. Laparoscopic surgery for the treatment of perirenal sclerosing liposarcoma is safe and effective.
