Abstract:
Objective To evaluate the CT findings of lymphofollicular thymic hyperplasia in adult myasthenia gravis (MG).Methods The CT findings of thymus area of 134 adult patients with lymphofolficular thymic hyperplasia in MG were reviewed,all of them with surgically and histologically proven diagnosis,and compared with the CT findings of 165 normal subjects.Results In the group of patient,CT showed enlargement of thymus in 31 patients,5 patients had nodule or mass(＜3 cm);thus 36 cases(26.9%)can confirmed diagnose by CT with thymic hyperplasia.CT showed 2 masses(＞3 em) and 9 patients(6.7%)had normal size thymus with soft-tissue density,it can considered with thymic hyperplasia.The spotty or streak shadow showed in other patients,though it could not be certain diagnosed as thymic hyperplasia,but could not be except it.The thymus area tissue complete replacement by fatty density were not found in patient group.The CT findings of patients had marked difference when compared with group of normal subjects(P＜0.01),except the spotty or streak shadows.Conclusion CT scan is an important method in diagnosing thymic lymphofollicular hyperplasia of MG in adult.
