Many reports have described adrenal myelolipomas but there have been only a few reports of extra-adrenal myelolipomas. We describe a 74-year-old woman who came to our observation for MRI of the lumbar spine for typical lumbar back pain. In addition to signs of mild scoliosis and spondylo disc arthrosis, MR imaging revealed a presacral mass showing a heterogeneously high signal in all pulse sequences and almost completely suppressed on inversion recovery sequences for fat tissue. CT imaging confirmed the fatty nature of the lesion and no signs of bone involvement. These findings were most consistent with a diagnosis of a rare presacral myelolipoma as confirmed at histopathologic analysis. This work reports a case of one of the rarest presacral masses, emphasizing the role of imaging in the differential diagnosis of other presacral masses.
许多报告都描述过肾上腺髓脂肪瘤，但肾上腺外髓脂肪瘤的报告却很少。我们描述了一位74岁女性，她因典型的腰背痛前来我院进行腰椎MRI检查。除了轻度脊柱侧弯和脊椎间盘关节病的体征外，磁共振成像显示骶前有一肿块，在所有脉冲序列中均表现为不均匀高信号，在脂肪组织的反转恢复序列上几乎完全被抑制。CT成像证实了病变的脂肪性质，且无骨受累迹象。这些发现最符合罕见的骶前髓脂肪瘤的诊断，组织病理学分析也证实了这一点。本文报告了一例极为罕见的骶前肿块病例，强调了影像学在鉴别其他骶前肿块中的作用。
