目的认识成人重症肌无力(MG)中胸腺淋巴样滤泡性增生的CT表现。方法复习134例经手术、病理确诊为胸腺淋巴样滤泡性增生的MG患者胸腺区的CT表现,并与165例正常人作了比较和统计学处理。结果病例组中有31例胸腺增大、5例直径＜3 cm的结节,共36例(26．9%)可在CT上确诊；9例(6．7%)呈形态正常但未增大的软组织密度胸腺、2例(1．5%)有＞3 cm的肿块被认为该病的可能性很大；其余病例在胸腺区内都有密集度不一的斑点、索条影；无一例胸腺区完全为脂肪取代。上述表现除斑片、索条影外,其余与正常对照组比较差异均有统计学意义(P＜0．01)。结论CT是在成人MG病例中诊断胸腺淋巴样滤泡性增生的重要方法。
Objective To understand the CT findings of thymic lymphoid follicular hyperplasia in adult myasthenia gravis (MG). Methods The CT findings of thymus in 134 MG patients with pathologically confirmed thymic lymphoid follicular hyperplasia were retrospectively reviewed and compared with 165 normal controls. Results Thirty-one thymus cases were found in the case group, and nodules with diameter <3 cm in 5 cases (26.9%) were diagnosed on CT. Nine cases (6.7%) were normal but not Large soft tissue density in the thymus, 2 cases (1.5%)> 3 cm mass is considered a great possibility of the disease; the remaining cases in the thymus area have different concentrations of spots, cable video; A thymus area is completely fat-substituted. In addition to the performance of the patch, cable video, the rest compared with the normal control group differences were statistically significant (P <0.01). Conclusion CT is an important method for the diagnosis of thymic lymphoid follicular hyperplasia in adult cases of MG.
