Myelolipoma is a rare, hormonally inactive, benign tumor consisting of fat and hematopoietic cells. It is often encountered in the adrenal gland. Less frequently, it may occur in extraadrenal sites. Although myelolipoma is well defined by criteria of morphologic imaging, functional characteristics may be crucial to exclude malignancy.We present a case of histologically proven extraadrenal myelolipoma which was successfully diagnosed by bone marrow scintigraphy, using a monoclonal antibody directed against myeloid elements.
髓脂肪瘤是一种罕见的、无激素活性的良性肿瘤，由脂肪和造血细胞组成。它常出现在肾上腺。较少见的情况下，也可能发生在肾上腺外部位。虽然髓脂肪瘤通过形态学成像标准可明确界定，但功能特征对于排除恶性肿瘤可能至关重要。我们报告一例经组织学证实的肾上腺外髓脂肪瘤病例，该病例通过使用针对髓系成分的单克隆抗体进行骨髓闪烁显像成功诊断。
