Thymoma is the most common primary tumor of anterior mediastinum and accounts for 20% of all mediastinal tumors. Although it can occur at any age, most patients are older than 40 years at the presentation. They are usually located anteriorly to the aortic arch but can occur in cardiophrenic angle.

It is the second most common mediastinal tumor in cats. Disease due to space occupying effects (lung compression) and paraneoplastic syndromes including myasthenia gravis, polymyositis, myocarditis, dermatitis and megaesophagus. Abstract: Thymoma is the commonest epithelial neoplasm arising from thymus gland. Tumour is slow growing and in the absence of metastasis, surgery is the treatment of choice. Radiology plays an important role in the initial evaluation of patients with thymic tumours. Patients with thymoma are typically adult men and women who usually present after the age of 40 years (in the fifth and sixth decades of life), although all age groups are affected. While many patients with thymoma are asymptomatic, approximately one-third present with chest pain, cough, dyspnea, and/or symptoms related to local invasion by the tumor (including superior vena cava syndrome).

Minimally invasive Thymoma and thymic carcinoma are diseases in which malignant (cancer) cells form in the thymus. Thymoma and thymic carcinoma, also called thymic epithelial tumors (TETs), are two types of rare cancers that can form in the cells that cover the outside surface of the thymus.The thymus is a small organ that lies in the upper chest above the heart and under the breastbone.

One study by Shibata et al. of 40 patients with thymoma identified 17 tumors as stage I, 17 tumors as stage II, 4 tumors as stage III, and 2 tumors as stage IV, demonstrating that SUV cannot predict the invasiveness of thymomas assessed by tumor stage . Another study included 37 thymoma patients who underwent FDG-PET-CT prior to surgery.

The normal thymus is visualized in the cranioventral mediastinum in young dogs as an inverted wedge shape known as a “sail sign” (Figure 1 ). It is usually inconspicuous by 1 year of age because of thymic involution.1.

Thymoma is the most common primary malignancy of the anterior mediastinum and the most common thymic epithelial neoplasm, but it is a rare tumor that constitutes less than 1% of adult malignancies. Computed tomography (CT) is currently the imaging modality of choice for distinguishing thymoma from o …

We aimed to develop and validate a combined radiomics nomogram for personalized prediction of histologic subtypes in patients with thymomas. A total of 182 thymoma patients were divided into training (n = 128) and test (n = 54) cohorts.
