Overview
Findings on CT scan suggestive of MG are mostly thymic masses such as thymic hyperplasia and thymoma.
CT
- CT scan may be helpful in the diagnosis of myasthenia gravis.
- Findings on CT scan suggestive of MG are mostly thymic masses.
- So many studies suggested a relationship between myasthenia gravis and thymus. This disease mostly occurs in patients with thymic hyperplasia and thymoma and the removal of thymus can reduce the clinical symptom of the patients.
- Based on this fact, detection of these thymic masses is very important in management of myasthenia gravis.[1][2][3][4][5]
- CT scan is very sensitive in identifying mediastinal masses but it’s not specific and it cannot differentiate thymomas from nonthymomatous masses.[6]
