【摘要】：目的:探讨肾上腺神经纤维瘤(ANF)的CT表现及其诊断价值。方法:搜集本院2001年-2016年经手术和病理证实的18例ANF患者的病例资料,其中男性8例,女性10例,年龄20岁2例,20~40岁11例,40岁5例。分析18例ANF的CT表现,并结合近年文献进行总结。结果:本组18例ANF患者,病灶部位右侧11例,左侧7例。肿瘤直径3.0~10.0cm,平均5.9cm。CT平扫表现为等或稍低密度,其中2例较大者可见液化坏死,5例见斑点状、小片状钙化,占27.8%,最大的肿瘤表现为低密度并可见分层。CT增强扫描表现为无强化、轻度强化或延迟强化。16例肿瘤与邻近组织分界清楚,占88.9%,2例较大者与右肾上级及下腔静脉有粘连,占11.1%;18例患者均未发现肿瘤周围及腹腔内肿大淋巴结。结论:肾上腺神经纤维瘤CT表现有一定特征,结合其临床表现能够做出提示性诊断。
[Abstract]:Objective: to investigate the CT findings of adrenal neurofibroma (ANFA) and its diagnostic value.Methods: the data of 18 cases of ANF confirmed by operation and pathology in our hospital from 2001 to 2016 were collected, including 8 males, 10 females, 2 patients aged 20 years, 11 patients aged 20 40 years, 5 patients aged 40 years.Ct findings of 18 cases of ANF were analyzed and summarized in recent years.Results: of the 18 patients with ANF, 11 were located on the right side and 7 on the left.The diameter of the tumor was 3.0 ~ 10.0 cm, and the average 5.9cm.CT plain scan showed equal or slightly low density. In 2 cases, liquefaction necrosis was seen in 5 cases, and small calcification was seen in 5 cases, accounting for 27.8%. The largest tumor showed low density and showed no enhancement on stratified .CT enhanced scan.The boundary between the tumor and adjacent tissues was clear in 16 cases with mild enhancement or delayed enhancement, accounting for 88.9 cases with adhesion to the superior right kidney and inferior vena cava. No enlarged lymph nodes around the tumor or in the abdominal cavity were found in 18 cases of mild enhancement or delayed enhancement.Conclusion: the CT features of adrenal neurofibroma can be used to make an indicative diagnosis.
