We report 2 cases of adrenal myelolipoma which were diagnosed definitively by ultrasonically guided percutaneous biopsy to waive surgery. In case 1, a 39-year-old man presented with abdominal pain. A right adrenal mass was detected by abdominal ultrasonography. In case 2, a 64-year-old man presented with nocturia. A space-occupying lesion above the left kidney was detected by excretory pyelography. Both cases were suspected of adrenal myelolipoma by ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI). The tumor size was 4 x 4 x 3 cm and 5 x 4.5 x 4 cm in cases land 2, respectively. In both cases percutaneous needle biopsy using ultrasonically guided puncture was performed. Histology showed a complex of hematopoietic and adipose tissues, corresponding to adrenal myelolipoma. The course has been uneventful without surgery for 58 months and 24 months, respectively. Percutaneous adrenal biopsy was useful to establish the definitive diagnosis and to select treatment options.
我们报告2例肾上腺髓样脂肪瘤，通过超声引导下经皮活检明确诊断，从而避免了手术。病例1，一名39岁男性，表现为腹痛。腹部超声检查发现右肾上腺肿块。病例2，一名64岁男性，表现为夜尿症。排泄性肾盂造影发现左肾上方有占位性病变。通过超声、计算机断层扫描（CT）和磁共振成像（MRI），两例均怀疑为肾上腺髓样脂肪瘤。病例1和病例2的肿瘤大小分别为4×4×3 cm和5×4.5×4 cm。两例均采用超声引导下经皮穿刺针活检。组织学显示造血组织和脂肪组织复合体，符合肾上腺髓样脂肪瘤。分别在未进行手术的情况下，病程平稳，已分别持续58个月和24个月。经皮肾上腺活检有助于明确诊断并选择治疗方案。
