title: Computed tomography of thymic abnormalities.
abstract: Computed tomographic examinations of 38 patients with surgically and histologically proven diagnosis were reviewed. Twenty subjects (52%) had an invasive thymoma and 16% an hyperplasic thymus. Myasthenia gravis was present in 6 cases (16%) of thymic abnormalities, four (10.5%) with invasive thymoma and two (5%) with thymic hyperplasia. Graves' disease was also present in one case of thymic hyperplasia. We emphasize the contribution of CT to the diagnosis and the prognosis.
