Overview
Thymoma can be largely diagnosed by using radiological techniques.
Diagnostic Study of Choice
Investigations:[1]
- Posterior-anterior (PA) and lateral X-ray of the chest are helpful in diagnosing most of thymomas.
- Among the patients who present with clinical signs of myasthenia gravis (MG), the CT Scan is the test of choice for the diagnosis of Thymoma.
- CT Scan with IV contrast and magnetic resonance imaging are helpful in determining the vascularity of the thymoma and helps in safe surgical removal of large tumors.
- PET Scan is very valuable in diagnosing the cases of invasive malignant thymoma.
- Thallium 201 single photon emission computed tomography is useful to distinguish normal thymic tissue from hyperplastic tissue or thymoma
- Ultrasonically guided core needle biopsy is used to obtain larger tissue specimens for histological examination. Annessi and colleagues[2] were able to diagnose thymoma in all patients that had undergone anterior mediastinal core needle biopsy by ultrasonic guidance with a sensitivity and specificity of 100%.
