Adrenal myelolipomas are usually small and asymptomatic tumors discovered incidentally. In a small number of cases, acute pain may develop secondary to intratumoral and/or retroperitoneal bleeding. We observed a large, surgically and histologically confirmed, myelolipoma of the right adrenal gland with spontaneous internal and external hemorrhage. CT demonstrated heterogeneity of the mass, obliteration of the surrounding fat planes, and retroperitoneal blood dissection. A literature review produced only 5 reports of ruptured myelolipoma with external hemorrhage.
肾上腺髓质脂肪瘤通常是偶然发现的小的无症状肿瘤。少数情况下，肿瘤内和/或腹膜后出血可继发急性疼痛。我们观察到一例经手术和组织学证实的右侧肾上腺巨大髓质脂肪瘤，伴有自发性内出血和外出血。CT显示肿块不均匀，周围脂肪间隙消失，腹膜后血液剥离。文献回顾仅发现5例有外出血的破裂髓质脂肪瘤报告。
