【摘要】：目的探讨肾上腺神经鞘瘤的临床特点、CT表现与肾上腺乏脂性皮质腺瘤的差异,提高对肾上腺神经鞘瘤的诊断水平。方法回顾性分析经手术病理证实的14例肾上腺神经鞘瘤和51例肾上腺乏脂性皮质腺瘤患者的CT表现,包括肿瘤部位、形态、大小、密度、边缘、钙化、囊变及强化方式等特点。结果高血压病史或血压升高症状,神经鞘瘤较乏脂腺瘤更少见(P=0.001)。病灶最长径神经鞘瘤普遍大于乏脂腺瘤(P0.001),而且神经鞘瘤最长径多≥5 cm(P0.001)。平扫肾上腺神经鞘瘤密度与乏脂腺瘤相比更加不均匀(P=0.028),且平扫CT值神经鞘瘤高于乏脂腺瘤(P0.001),而动、静脉期神经鞘瘤强化值均低于乏脂腺瘤(P均0.001)。神经鞘瘤强化程度较乏脂腺瘤低(P=0.008),而神经鞘瘤囊变较乏脂腺瘤更常见(P0.001)。结论肾上腺神经鞘瘤的CT表现有一定的特征性,与乏脂腺瘤有差异。
[Abstract]:Objective to investigate the clinical features and CT findings of adrenal neurilemmoma and the difference between adrenal and lipoid cortical adenomas, and to improve the diagnostic level of adrenal neurilemmoma. Methods the CT findings of 14 cases of adrenal neurilemmoma and 51 cases of adrenal cortical adenoma proved by operation and pathology were retrospectively analyzed, including location, shape, size, density, edge, calcification, cystic degeneration and enhancement mode. Results the history of hypertension or the symptoms of blood pressure increased, and the neurilemmoma was more rare than that of the adenoma (P=0.001). The longest diameter of lesion schwannoma is generally greater than lipid poor adenomas (P0.001), and the longest diameter of more than 5 schwannomas (cm P0.001). The density of adrenal neurilemmoma in plain scan was more uneven than that in patients with lipoid adenoma (P=0.028), and plain scan CT value was higher than that in low fat adenoma (P0.001), and the enhancement value of schwannoma in dynamic and venous phase was all lower than that in fat deficient adenoma (P 0.001). The enhancement degree of neurilemmoma was lower than that of the adenoma (P=0.008), but the cystic change of neurilemmoma was more common than that of the adenoma (P0.001). Conclusion the CT features of the adrenal neurilemmoma are characteristic, which are different from those of the adenoma.

【正文快照】： 神经鞘瘤是一类周围神经肿瘤,起源于神经鞘膜施旺细胞,故又称施旺细胞瘤(Schwannoma),由Verocay于1932年首次描述。神经鞘瘤好发于外周神经及听神经,发生在腹膜后的神经鞘瘤约占0.5%~5%[1],原发于肾上腺髓质的神经鞘瘤更是罕见,多为良性。多数学者认为其来源于肾上腺髓质交感
