== Overview ==
Thymoma can be largely [[Diagnosis|diagnosed]] by using [[Radiology|radiological]] techniques.

===Study of Choice===
*[[Anatomical terms of location|Posterior]]-[[Anatomical terms of location|anterior]] (PA) and [[lateral]] [[Chest X-ray|x-ray of the chest]] are helpful in [[Diagnosis|diagnosing]] most of the thymomas.


=== Study of choice ===
* Among the [[Patient|patients]] who present with [[clinical]] signs of [[myasthenia gravis|myasthenia gravis (MG)]], [[Computed tomography|CT scan]] is the test of choice for the [[diagnosis]] of thymoma.
[Name of the investigation] is the gold standard test for the diagnosis of [disease name].
* [[Computed tomography|CT scan]] with [[IV]] [[contrast]] and [[Magnetic resonance imaging|MRI]] are helpful in determining the [[vascularity]] of the thymoma and helps in safe [[Surgery|surgical]] removal of large [[Tumor|tumors]].
*[[Positron emission tomography|PET scan]] is very valuable in [[Diagnosis|diagnosing]] the cases of [[Invasive (medical)|invasive]] [[malignant]] thymoma.<ref name="pmid26273398">{{cite journal| author=Scagliori E, Evangelista L, Panunzio A, Calabrese F, Nannini N, Polverosi R et al.| title=Conflicting or complementary role of computed tomography (CT) and positron emission tomography (PET)/CT in the assessment of thymic cancer and thymoma: our experience and literature review. | journal=Thorac Cancer | year= 2015 | volume= 6 | issue= 4 | pages= 433-42 | pmid=26273398 | doi=10.1111/1759-7714.12197 | pmc=4511321 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=26273398  }} </ref>
* Thallium 201 single photon emission [[computed tomography]] is useful to distinguish normal [[Thymus|thymic]] [[Tissue (biology)|tissue]] from [[Hyperplasia|hyperplastic]] [[Tissue (biology)|tissue]] or thymoma
*[[Medical ultrasonography|Ultrasonically]] guided core [[Needle aspiration biopsy|needle biopsy]] is used to obtain larger [[Tissue (biology)|tissue]] specimens for [[histological]] [[examination]].
*Annessi and colleagues were able to [[Diagnosis|diagnose]] thymoma in all [[Patient|patients]] who had undergone [[Anterior mediastinum|anterior mediastinal]] core [[needle biopsy]] by [[Medical ultrasonography|ultrasonic]] guidance with a [[sensitivity]] and [[specificity]] of 100%.

Staging

  • The thymic epithelial tumor staging system was initially proposed by Bergh and his colleagues in 1978, modified by Wilkins and Castleman in 1979, and further developed by Masaoka et al. in 1981.[2][3][4][5]
  • Modified Masaoka staging grouped with TNM classification is the most widely adopted system for thymic epithelial tumors currently in use.
