Adrenal myelolipoma is a rare benign tumor composed of mature lipomatous and hemopoietic tissue. Although it is often discovered as an incidental finding on imaging of the abdomen for some other reason or at autopsy, adrenal myelolipoma has been reported to present with symptoms such as flank pain resulting from tumor bulk, necrosis, or spontaneous retroperitoneal hemorrhage. Myelolipomas are hormonally inactive but have also been reported to coexist with other hormonally active tumors of the adrenal gland. They are usually unilateral but may be bilateral and may also develop in extraadrenal sites like the retroperitoneum, thorax, and pelvis. We report a patient with symptomatic adrenal myelolipoma diagnosed on computed tomography scan and confirmed on computed tomography-guided biopsy. The patient underwent surgical resection for symptomatic relief. We also review the literature to evaluate the presentation and optimal management of this rare adrenal tumor that is not encountered by most general surgeons and therefore not well known to most surgeons.
肾上腺髓脂肪瘤是一种罕见的良性肿瘤，由成熟的脂肪组织和造血组织组成。尽管它常常因其他原因在腹部影像学检查时偶然发现，或在尸检时被发现，但据报道，肾上腺髓脂肪瘤可出现因肿瘤体积、坏死或自发性腹膜后出血导致的胁腹痛等症状。髓脂肪瘤无激素活性，但也有报道称其与肾上腺其他有激素活性的肿瘤共存。它们通常为单侧，但也可能双侧发生，还可能发生于肾上腺外部位，如腹膜后、胸部和骨盆。我们报告一例经计算机断层扫描诊断并经计算机断层扫描引导下活检证实的有症状肾上腺髓脂肪瘤患者。该患者接受了手术切除以缓解症状。我们还回顾了文献，以评估这种大多数普通外科医生未遇到、因此大多数外科医生不太了解的罕见肾上腺肿瘤的临床表现和最佳治疗方法。
