目的探讨肾上腺髓脂瘤的CT特征及其病理基础,以提高其CT诊断水平。方法对12例经手术及病理学检查证实的肾上腺髓脂瘤患者的临床及影像学资料进行回顾性分析。在CT图像上,观察病变的位置、大小、形态、密度、内部结构及其与周围结构的关系,并结合病理学特征进行分析。结果 12例肾上腺髓脂瘤发生在左侧2例,右侧9例,双侧1例。CT特征表现为以脂肪密度为主的混杂密度肿块。病理学检查显示肿瘤由成熟脂肪细胞和骨髓造血细胞组成。术前CT诊断与术后病理学检查结果符合者为11/12例。结论肾上腺髓脂瘤虽然较为少见,但其病理成分特殊,CT表现极具特征性,结合临床和化验检查,术前完全能够正确诊断。
Objective To investigate the CT features of adrenal myeloma and its pathological basis in order to improve its CT diagnostic level. Methods The clinical and imaging data of 12 adrenal myeloma patients confirmed by operation and pathology were analyzed retrospectively. On the CT images, the location, size, shape, density, internal structure of the lesion and its relationship with the surrounding structures were observed, and the pathological features were analyzed. Results 12 cases of adrenal myeloma occurred in 2 cases on the left, 9 cases on the right and 1 case on both sides. CT features manifested as a fat density-based mass density lumps. Pathological examination revealed that the tumor consisted of mature adipocytes and myeloid hematopoietic cells. Preoperative CT diagnosis and postoperative pathological findings were consistent with 11/12 cases. Conclusion Adrenal myeloma is relatively rare, but its pathological components are special. The CT features are very characteristic. Combined with clinical and laboratory tests, it can diagnose completely before operation.
