Renal angiomyolipoma: report of 24 cases

A series of 24 patients with renal angiomyolipoma was reviewed. Their ages ranged from 10 to 70 years (average 41). Four cases were associated with tuberous sclerosis, 1 with spinal neurilemmoma, 1 with transitional cell carcinoma and another with renal tuberculosis. The presenting symptoms in decreasing frequencies were flank pain, mass, haematuria, fever, syncope and respiratory distress. Although it has often been said that angiomyolipomas associated with tuberous sclerosis are small and asymptomatic, all 4 such patients in this study had large symptomatic tumours. Before the advent of CT scan and ultrasonography, the pre-operative diagnostic rate for cases unassociated with tuberous sclerosis was 10% (1/10). With the combined use of these 2 modalities, the diagnostic rate increased to 60% (6/10). Most patients in this series were treated with nephrectomy. However, equally good outcomes occurred in 2 patients who received partial nephrectomies. Pre-operative diagnosis now makes it possible to consider more conservative management.     

Renal angiomyolipoma imaging: report of 9 cases

PURPOSE: To report the radiological polymorphism of angiomyolipoma (AML). MATERIEL AND METHODS: A retrospective series of eight cases of AML explored by US and CT scan. The diagnosis was radiological in seven cases and histopathological in one case. RESULT: Five cases of AML were discovered fortuitously. The tuberous sclerosis of Bourneville disease (TSB) was noted in five cases. The cverage age was 37 years with female predominance noted in seven cases. The AML were multiple in half cases all of thein had TSB. The tumoral size ranged from 0.5 cm and 20 cm. The US showed an homogenous hyperechogenique mass in six cases and heterogenous in two cases. The CT scan showed polymorph parenchymal lesions. The fatty component was detected in seven cases. An intratumoral bleeding was noted in one case. CONCLUSION: The radiological feature of AML is variable, related to tumoral size. It's typical when a tumor of kidney contains fat. An association with TSB is a supplementary argument of diagnosis.     

Renal epithelioid angiomyolipoma: 2 Cases report

Introduction

The 2004 World Health Organization Classification of Renal Neoplasms defined epithelioid angiomyolipoma as a potentially malignant mesenchymal neoplasm, characterized by a proliferation of predominantly epithelioid cells with approximately one third of patients experiencing metastases and one half of them having a history of tuberous sclerosis complex.

Renal angiomyolipoma: report of 2 cases of tuberous sclerosis in female siblings

Two cases of renal angiomyolipomas in female siblings associated with tuberous sclerosis were reported. The first case was a 47-year-old housewife who visited the hospital because of severe right flank pain. Bilateral renal angiomyolipomas and hemorrhage in the right angiomyolipoma were recognized by computerized tomography, ultrasonography and renal angiography. After 2 months she had another episode of left flank pain and was diagnosed to have hemorrhage in the left renal tumor. The pain remissed by conservative treatment. Bilateral nephrectomy and hemodialysis would be necessary if she were to have a third attack. The second case was her 36-year-old sister with the chief complaint of left flank pain and genital bleeding. CT and renal angiography suggested a large angiomyolipoma in her left kidney and a small one in her right kidney. Left nephrectomy, right partial nephrectomy and hysterectomy were performed to prevent intratumoral hemorrhage. The histopathological diagnosis was angiomyolipoma of kidneys, uterus and lymphnodes of right renal hilus. Although pre-operative differentiation of angiomyolipoma from renal cell carcinoma has been difficult, recently diagnosis has become possible by CT, ultra-sonography and angiography.

肾血管平滑肌脂肪瘤自发性破裂(附23例报告)

目的 探讨肾血管平滑肌脂肪瘤(RAML)自发性破裂的临床表现、诊断和治疗。方法 肾血管平滑肌脂肪瘤自发破裂23例，临床表现突发腰腹疼痛者21例，腰部酸胀者2例；其中伴血尿3例、恶心呕吐2例、休克3例、发热1例。23例B超检查，确诊13例；CT检查21例，确诊16例。结果 术前确诊RAML者16例，术中冰冻切片确诊2例，误诊为肾癌者4例、肾感染性病变者1例。行肾切除10例，肾部分切除和肿瘤剜除术各6例，数字减影血管造影(DSA)加栓塞术1例。结论 RAML自发性破裂后常改变临床症状和影像学特征，导致误诊和肾切除，综合分析临床表现和影像学资料可以提高术前确诊率，术中冰冻切片可以避免不必要的肾切除。

Renal angiomyolipoma with marked extrarenal development: a case report

A 28-year-old female complained of minimal fever elevation. Computed tomography (CT) revealed a left renal tumor of 10 cm in diameter. Ultrasonogram and CT, magnetic resonance imaging and angiography suggested a renal angiomyolipoma (AML) with marked extrarenal development. Partial nephrectomy was performed using a microwave tissue coagulater without clamping of the renal artery. The tumor weight was 800 g and the pathological diagnosis was AML. The management of large AML is reviewed in the literature. Nephron sparing surgery should be performed even in patients who have a larger tumor with extrarenal development.
