Embolization of Ruptured Renal Angiomyolipoma in Puerpera

Abstract

Angiomyolipomas (AMLs) are rare benign tumors derived from mesenchymal tissue and composed of varying degrees of adipose tissue, muscle and blood vessels. Renal AMLs (RAMLs) are the result of a sporadic event, and, in most of cases, the diagnosis is usually incidental, but hemorrhage and shock may be present. During pregnancy, the size of AMLs may increase and they may rupture, probably due to the high expression of hormone receptors, and the increase in maternal circulation and abdominal pressure. The authors present a case of a woman with ruptured RAML submitted to urgent endovascular treatment four days after giving birth by cesarean section.

Endovascular Treatment of Renal Angiomyolipoma Rupture - Case Report

“…The follow-up of patients remains a controversial subject, but there are recommendations established in the literature. Asymptomatic patients with masses smaller than 4 cm must be monitored with ultrasonography or computed tomography every 6 months 5 .…”

Transfemoral embolization of a large symptomatic renal angiomyolipoma in a horseshoe kidney: a case report and literature review

“…enal angiomyolipomas (AML) are benign renal neoplasms composed of blood vessels, adipose tissue and smooth muscle in varying amounts. They are commoner in females, especially in the 4 th -5 th decade and may occur spontaneously in association with Tuberous sclerosis or rarely with Lymphangioleiomyomatosis [1,2]. They constitute the most common benign renal neoplasia with a reported incidence of about 0.3 -3% [3,4].…”
