Myelolipoma is an uncommon benign tumour composed of mature fat tissue and haematopoietic elements and is most commonly found in the adrenal gland. We report a case, which was discovered incidentally on chest X-ray, of a rare occurrence of multifocal extra-adrenal myelolipoma in the thoracic paravertebral region. This was further investigated with multi-detector computed tomography and magnetic resonance imaging. The presumed diagnosis, of extra-adrenal myelolipoma, was histologically confirmed via tissue sample obtained by computed tomography guided biopsy. We compare the adrenal and extra-adrenal entities from the perspective of published literature and also review the cases, published in Pubmed, of extra-adrenal myelolipomas in order to summarize the different locations of this lesion.
髓脂肪瘤是一种由成熟脂肪组织和造血成分组成的罕见良性肿瘤，最常见于肾上腺。我们报告一例在胸部X线检查时偶然发现的病例，该病例为罕见的胸段椎旁区域多灶性肾上腺外髓脂肪瘤。通过多排螺旋计算机断层扫描和磁共振成像对其进行了进一步检查。通过计算机断层扫描引导下活检获取的组织样本，在组织学上证实了肾上腺外髓脂肪瘤的初步诊断。我们从已发表文献的角度比较了肾上腺和肾上腺外的情况，并回顾了发表在PubMed上的肾上腺外髓脂肪瘤病例，以总结该病变的不同位置。
