Spontaneous rupture of a renal angiomyolipoma

A case of spontaneous hemorrhage in the retroperitoneal space, secondary to an angiomyolipoma of the kidney is reported in a 33 year old woman admitted with an acute abdomen. Differential diagnosis is discussed.     

Spontaneous rupture of renal angiomyolipoma: a case report

A 55-year-old woman presented with sudden right lower abdominal pain. Computed tomography demonstrated retroperitoneal hematoma associated with minus-density area, diagnosed as spontaneous rupture of angiomyolipoma. Super-selective transarterial embolization was performed, but anemia and right abdominal pain became worse in spite of conservative therapy including transfusion, indicating re-rupture of the renal tumor. Although partial nephrectomy was planned, right nephrectomy was finally performed because of massive intraoperative bleeding. Accurate diagnosis and prompt treatment are required when life-threatening rupture of renal tumor is suspected.     

Spontaneous rupture of renal angiomyolipoma. Report of three cases

The presentation of renal angiomyolipoma as an acute abdominal condition, together with hypovolemic shock, is very rare. 3 such cases are described herein with special reference to the diagnostic problems and recommended management.     

Spontaneous rupture of a renal angiomyolipoma in pregnancy: a case report]

A 32-year-old woman in the 36th week of pregnancy was admitted to obstetrics with a complaint of left flank pain. Magnetic resonance imaging demonstrated a left perinephric hematoma before the cesarean section. Spontaneous rupture of renal angiomyolipoma was suspected by computed tomographic scan and renal angiography after the cesarean section. We attempted partial nephrectomy, but performed nephrectomy because of perinephric adhesion. This is the 11th case of spontaneous rupture of renal angiomyolipoma during pregnancy in the Japanese literature.

Spontaneous renal allograft rupture

Rupture of an allografted kidney occurred in five patients 5-17 days after transplantation. In one patient the microscopic pathological changes corresponded with the nodose polyarteritis pattern. In four patients interstitial rejection nephritis with severe haemorrhage and haematoma was found. It is suggested that the bleeding is due to peristatic hyperaemia and defects in the inner elastic membranes. In one case multifocal necrotizing arteriopathy was the main pathogenetic factor.     

肾血管平滑肌脂肪瘤自发性破裂危险因素

目的 观察肾血管平滑肌脂肪瘤(RAML)自发性破裂的危险因素。方法 纳入151例接受超选择性栓塞的RAML患者,根据治疗前CT或血管造影是否可见对比剂外溢将其分为破裂组(n=45)及未破裂组(n=106);比较组间患者基本资料及肿瘤影像学表现的差异,以多因素logistic回归分析观察RAML破裂的独立危险因素,构建风险预测模型并以列线图可视化;绘制受试者工作特征(ROC)曲线,评价以各危险因素及模型判断RAML破裂的效能。结果 组间肿瘤最大径、瘤内动脉瘤最大径＞5 mm占比差异均有统计学意义(P均＜0.05)。ROC曲线分析结果显示,以6.32 cm为截断值,根据肿瘤最大径判断RAML破裂的曲线下面积(AUC)为0.684。多因素logistic分析显示,单发肿瘤、直径较大及瘤内动脉瘤最大径≥5 mm(OR=0.37、1.14、5.69,P均＜0.05)是RAML破裂的独立危险因素;以之构建的预测RAML破裂风险模型预测RAML破裂的AUC为0.776,且模型校准曲线与理想曲线的重合度尚可。结论 单发病灶、肿瘤较大且存在≥5 mm的瘤内动脉瘤是RAML自发性破裂的独立危险因素。     

巨大肝脏血管平滑肌脂肪瘤自发性破裂一例

病例 患者男性,69岁,主诉:右上腹持续性隐痛伴腹胀1周.既往无肝炎、寄生虫病史.查体:右侧腹部扪及一巨大肿块,向上与肝相续,向下达髂前上棘水平.实验室检查:肝炎病毒系列阴性,肝功能正常, AFP 1.59 U/mL,CA1998.52 U/mL,CEA 0.49 ng/mL. 腹部增强CT提示:肝脏一外生性稍低密度肿...     

Spontaneous rupture of renal transplants

Spontaneous rupture of transplanted kidneys, although uncommon, requires recognition in view of the increasing number of patients subjected to renal transplantation. The etiologic mechanism of spontaneous rupture and our experience with hyperacute rejection associated with spontaneous rupture are discussed. Immunopathologic aspects of hyperacute rejection are correlated with the clinical course, diagnosis, and treatment of spontaneous rupture of transplanted kidneys.     

Spontaneous rupture of renal angiomyolipoma with tuberous sclerosis during long-term follow-up: a case report]

We present a case of spontaneous rupture of bilateral renal angiomyolipoma (AML) with tuberous sclerosis. A 46-year-old woman was admitted with sudden onset of severe left flank pain. She had been diagnosed to have bilateral AML with tuberous sclerosis 15 years earlier. Four years after the initial diagnosis, spontaneous rupture of right renal AML occurred and right renal embolization of the right renal artery was performed. The treatment for the left renal AML was not performed. Eleven years later in 2000, spontaneous rupture of contralateral renal AML occurred and left renal embolization of the left renal artery was performed. We evaluated the efficacy of selective arterial embolization in right AML and the change of the tumor size during a 10-year follow up after embolization. The right AML had decreased 86% in 11 years. Selective arterial embolization is an effective and safe treatment for AML. We evaluated the natural history of left AML and calculated the doubling time to be about 1,370 days for the first period of 4 years and about 2,075 days for the second period of 11 years. Although the growth change was very slow, we should observe the tumors carefully on computed tomography or ultrasound to prevent life-threatening hemorrhage.

Spontaneous rupture of renal pelvis

A seventy-seven-year-old female with progressive abdominal signs for twenty-four hours was found to have had a spontaneous rupture of the renal pelvis with massive urinary extravasation.     

Spontaneous renal rupture in pregnancy

A review of the literature reveals 9 cases of spontaneous renal rupture in pregnancy, to which we add another case. Most cases occurred in hydronephrotic kidneys. Four cases consisted of renal rupture without associated infection or tumor, 3 were associated with abscesses, and 3 ruptured through renal hamartomas. Previously, all ruptured kidneys were removed. In our case the kidney was salvaged satisfactorily by prompt placement of a nephrostomy tube and drainage of the perirenal tissue. Attempt at renal salvage is urged for renal rupture in pregnancy.     

肾错构瘤破裂出血的急诊处理

目的：探讨肾错构瘤(RAML)破裂出血的诊治方法。方法：回顾性分析11例RAML破裂出血的急诊处理过程。结果：11例患者均经病理明确诊断，4例行患肾切除术，2例行肾部分切除术，5例行肿瘤切除术。11例患者均恢复良好。结论：B超和CT检查为术前确诊主要依据；对RAML破裂出血应采取积极的治疗态度；手术治疗仍为主要治疗方法。
