Adrenal Myelolipoma Presenting with Spontaneous Rupture and Retroperitoneal Hemorrhage: A Case Report

Abstract

Adrenal myelolipoma is a rare, benign tumor that is commonly small and non-functioning. It generally comprises adipocytes and mature hematopoietic elements. It occurs unilaterally and originates from the adrenal cortices in most cases (1). Most adrenal myelolipomas are asymptomatic and detected incidentally by imaging modalities such as ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) (1, 2). However, in rare cases, they may be symptomatic when the tumor size is large enough to compress adjacent structures or when tumor rupture causes hemorrhage (1, 3). Spontaneous retroperitoneal hemorrhaging from an adrenal myelolipoma is uncommon (1). Herein, we reported a case of adrenal myelolipoma with spontaneous retroperitoneal hemorrhage and briefly reviewed the relevant literature. CASE REPORT
