Lower:Axial CT scan of the upper chest shows a non-enhancing lobulated but sharply marginated anterior mediastinal mass (yellow arrow).. For these same photos, click here and here Thymomas are fascinating tumors because of their multifaceted clinical presentation, including an unrivaled frequency of associated paraneoplastic autoimmune diseases and an astounding histologic heterogeneity. Thymoma is often divided into “noninvasive” and “invasive” types.

Thymic lesions include thymoma, thymic hyperplasia, invasive thymoma, thymic carcinoma, and carcinoid. 18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) may assist with the characterization of thymic lesions. A thymoma is a tumor originating from the epithelial cells of the thymus that is considered a rare malignancy. Thymomas are frequently associated with the neuromuscular disorder such as myasthenia gravis; thymoma is found in 20% of patients with myasthenia gravis. Accurately predicting the WHO classification of thymomas is urgently needed to optimize individualized therapeutic strategies. 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.

Thymoma and thymic carcinoma are usually diagnosed, staged, and treated during surgery. Radiology 1996;201(2):471–474.

The World Health Organization histologic classiﬁcation system reﬂects the oncological behavior of thymoma: A clinical study of 273 patients. Thymoma is the most common primary neoplasm of the anterior mediastinum, but it accounts for <1% of all adult malignancies. It is the most common of the thymic epithelial neoplasms, which, in addition to thymoma, include thymic carcinoma and thymic carcinoid.Because of the rarity of thymoma, it has not been studied thoroughly.Over the last half decade, there has been increased interest in this 2020-07-22 Introduction.

Differentiation of thymoma/non‐thymoma based on the peak time of dynamic MR imaging showed optimal sensitivity (79%) and specificity (84%) when defining thymomas as lesions having peak time appearing earlier than 2 min and non‐thymomas later than 2.5 min, with an accuracy of 81%.
