31 cases of elderly patients with myasthenia gravis thymus lesions CT and pathologic correlation


Higher. Elderly MG patients with thymus pathological changes in the difference between the young group, requires further accumulation of clinical data. CT diagnosis of thymic hyperplasia abnormality rate is low compared with the abnormal pathology, which is MG patients with thymic hyperplasia on pathological features. MG patients with thymus hyperplasia thymus compared with healthy people, the most significant difference is the formation of germinal centers of lymphoid follicles. Because germinal centers of lymphoid follicles is a normal size gland, it may be a diffuse enlarged gland or glands showed massive local group,[link widoczny dla zalogowanych], which was dotted in the pathological and cord-like hyperplasia of the thymus can be presented in the CT atypical manifestations,[link widoczny dla zalogowanych], CT showed a normal size of the gland or in spots,[link widoczny dla zalogowanych], typical of cable shall not affect the performance of thymic hyperplasia prone to misdiagnosis,[link widoczny dla zalogowanych], was part of the performance of block thymus gland hyperplasia misdiagnosed as thymoma. Owing to the MG patients with thymus area often spots, such as the cable does not affect the performance of a typical CT as CT were normal,[link widoczny dla zalogowanych], leading to abnormal CT diagnosis of thymic hyperplasia was low [2. To improve the imaging sensitivity of diagnosis of thymic hyperplasia, has been reported using functional imaging, the diagnosis of thymic hyperplasia with high sensitivity than CT]. Future, preoperative examination of how to further improve on the old MG detection rate in patients with abnormal thymus remains to be further studied.
