肾囊性淋巴管瘤一例报告及文献复习

Lymphangioma of the renal capsule (a case report and review of literature)

目的 探讨肾囊性淋巴管瘤的临床诊治特点。 方法 报告 1例肾囊性淋巴管瘤患者临床资料 ,结合文献复习讨论。患者男性 ,38岁。主要临床表现为血尿、腰部钝痛、肾绞痛和肾区肿块 ,B超、CT、检查显示为囊性病变 ,内有分隔 ,囊液回声、密度、信号显示为水性、浆液性、血性。 结果 患者经开放性手术治疗后痊愈。术后病理检查囊壁内发现平滑肌及内衬上皮细胞 ,囊壁和囊腔内发现淋巴细胞。患者术后随访 6个月未见复发。 结论 肾囊性淋巴管瘤B超、CT、MRI检查无特征性改变时 ,经皮细针穿刺活检和囊液细胞学检查可能有助于诊断。确诊需病理组织学检查。外科治疗效果良好。

Objective To study the clinical features of renal lymphangioma and to improve the diagnosis and treatment of the disease. Methods A 38-year-old male patient with renal lymphangi oma was reported and the relevant literature was reviewed.The main manifestation s were hematuria,flank pain,renal colic and palpable mass.The diagnosis of renal lymphangioma was based on the B-ultrasound and CT findings which showed cystic pathologic changes.The echo,density and signal of the cystic fluid indicated th at it was watery,serous fluid or hemorrhagic fluid. Results The patient underwent open surgery.Postoperative pathology found smooth musc les and the lining epithelial cells in the cystic wall,and lymphocytes in the cy stic wall and fluid,which confirmed the diagnosis.Follow-up of 6 months showed no recurrence. Conclusions No characteristic change can be found by B-ultrasound,CT scan and MRI examinations in renal lymphangioma.Fi ne needle aspiration and cytological examination of the fluid may help confirm t he diagnosis.The histopathological diagnosis is most important.Surgical manageme nt (radical or partial nephrectomy) has good outcomes.
