[Correlation of computer tomography findings with surgical findings in patients with myasthenia gravis].

A group of patients with myasthenia gravis operated at the Third Surgical Clinic, Faculty Hospital had in 20.5% a thymoma. Before operation CT did not detect the thymoma in 13.8% of the thymomas detected during operation and verified by histological examination. This fact must be taken into account when indicating conservative treatment in a myasthenic patient.
