WHO types B1–B3: malignant thymoma, lymphocytic, cortical, epithelial. WHO type C: highly malignant, thymic carcinoma, clear cell/sarcomatoid types. thymolipoma / thymoliposarcoma. thymic cyst. congenital (contains thymic tissue in wall) secondary to thoracotomy. following chemotherapy or radiotherapy for mediastinal tumors.

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. Thymoma is linked with myasthenia gravis and other autoimmune diseases. Signs and symptoms of thymoma and thymic carcinoma include a cough and chest pain.

23 Aug 2011 Chest imaging studies typically show a round or lobulated tumor in the anterior mediastinum. Calcifications in thymomas are classically punctuate

Histology: The tumor is a thymoma of the cortical type. The mass is firm and covered anterolaterally with a thin translucent membrane, consistent with mediastinal pleura. The cut surface is yellow-tan 2010-10-01 Thymoma is the most common primary neoplasm of the anterior mediastinum, but it accounts for <1% of all adult malignancies.

Oval round or lobulated soft tissue mass, sharply demarcated, usually smaller than teratomas Usually occur in upper third of chest around the heart and great vessels, which they may displace posteriorly Thymomas may spread along pleural reflections to posterior mediastinum, diaphragm and …

They are usually located anteriorly to the aortic arch but can occur in cardiophrenic angle. The tumor is a thymoma of the cortical type.

Case of the Week 558 on award-winning, radiologic teaching site for medical students and those starting out in radiology focusing on chest, GI, cardiac and musculoskeletal diseases containing over 300 PowerPoint lectures, quizzes, hand-out notes, interactive material, most commons lists and pictorial differential diagnoses Dr. Adrien Hespel provides the radiology perspective on this thymoma case. 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. Figure 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 … 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%.

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.

Tests that examine the thymus are used to detect (find) thymoma or thymic carcinoma. Thymoma and thymic carcinoma are usually diagnosed, staged, and treated during surgery.

The thymus is in the ant mediastinum (MN), involved in the processing and maturation of T lymphocytes to recognize foreign antigens from “self” antigens. What structures are located in the ant, middle, and post MN? Anterior: LNs, thymus, mesenchymal tissues

The age at manifestation ranges from 32 to 83 years, with a mean age of 61 years. 1 Type A thymoma may have an associated autoimmune disorder, including but not limited to myasthenia gravis (4% to 24%), Good syndrome, and pure red cell Accurately predicting the WHO classification of thymomas is urgently needed to optimize individualized therapeutic strategies.
