Angiomyolipomas are benign mesenchymal lesions often diagnosed incidentally, composed of adipose tissue, dysmorphic blood vessels, and smooth muscle. They are usually unilateral and symptomatic only when larger than 4 centimeters, posing a risk of spontaneous rupture and severe retroperitoneal hemorrhage. Treatment varies from conservative management to selective embolization or nephrectomy, depending on tumor size and patient condition. This case report describes a 26-year-old female with a giant renal angiomyolipoma treated with angioembolization, who subsequently developed postembolization syndrome.
