Myelolipomas are rare benign tumors made up of adipose and hematopoietic tissue that commonly occur in the adrenal glands unilaterally. Spontaneous hemorrhage occurs in < 5% of these tumors, and often present as large masses. A 50-year-old male presented with right flank pain that had been growing increasingly worse over a two-week period. Contrast-enhanced Computed Tomography (CT) revealed a large suprarenal 15-cm mass exerting mass effect on the kidney and liver along with possible hemorrhage. T1 fat saturated and T2 non-fat saturated magnetic resonance imaging (MRI) confirmed the diagnosis of a myelolipoma with hemorrhage. The patient was treated with surgical resection of the mass and the follow-up pathology report confirmed a giant hemorrhagic adrenal myelolipoma. Spontaneous hemorrhage of a large myelolipoma measuring 15 cm is a rare entity and the correct imaging needs to be done in order to carry out the appropriate treatment.
肾上腺髓质脂肪瘤是一种罕见的由脂肪组织和造血组织构成的良性肿瘤，通常单侧发生于肾上腺。这些肿瘤中不到5%会发生自发性出血，且常表现为较大肿块。一名50岁男性因右侧胁腹疼痛就诊，该疼痛在两周内逐渐加重。增强计算机断层扫描（CT）显示一个15厘米的巨大肾上腺肿块，对肾脏和肝脏产生占位效应，同时可能存在出血。T1脂肪饱和及T2非脂肪饱和磁共振成像（MRI）确诊为伴有出血的肾上腺髓质脂肪瘤。患者接受了肿块手术切除，后续病理报告证实为巨大出血性肾上腺髓质脂肪瘤。一个15厘米的大肾上腺髓质脂肪瘤发生自发性出血是一种罕见情况，需要进行正确的影像学检查以便实施恰当的治疗。
