Myelolipomas are uncommon, benign tumors which typically occur in the adrenal glands and consist of mature adipose tissue and benign hematopoietic components. Myelolipomas can occur outside of the adrenal glands, but the presacral region, retroperitoneum, pelvis, and mediastinum are unusual locations for these tumors. It is important to recognize this entity in these locations since they can attain massive sizes leading to pressure symptoms and need to be differentiated from the malignant tumors like liposarcomas. We present a myelolipoma case in the presacral region. Our case illustrates the clinical approach of these tumors in such unusual locations.
肾上腺髓质脂肪瘤是一种罕见的良性肿瘤，通常发生于肾上腺，由成熟的脂肪组织和良性造血成分组成。肾上腺髓质脂肪瘤也可发生于肾上腺外，但骶前区、腹膜后、盆腔和纵隔是这些肿瘤不常见的发生部位。在这些部位识别该病变很重要，因为它们可能长得很大并导致压迫症状，且需要与脂肪肉瘤等恶性肿瘤相鉴别。我们报告一例骶前区肾上腺髓质脂肪瘤病例。我们的病例说明了这些肿瘤在如此不常见部位的临床处理方法。
