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. Radiomics features were If your hospital, university, trust or other institution provides access to BMJ Best Practice through services such as OpenAthens or Shibboleth, log in via this button: 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.

Two cases of ectopic cervical thymoma are presented. These cases both manifested as mass lesions at the thoracic inlet, displacing the trachea, and were originally misdiagnosed as thyroid masses. The masses had clinical features similar to those previously reported for cervical thymoma: preponderance in women, benign clinical course, and absence of myasthenic symptoms.

WHO type C: highly malignant, thymic carcinoma, clear cell/sarcomatoid types. 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 … Two cases of ectopic cervical thymoma are presented.

Detterbeck FC. Clinical value of the WHO classification system of thymoma. Method: The CT scans from 27 patients with invasive thymoma and 23 with noninvasive thymoma were independently assessed by two observers without knowledge of their invasiveness. The presence and distribution of various CT findings were independently analyzed. Reliable unenhanced and contrast-enhanced imaging is fundamental for distinguishing between cystic and solid masses of the thymus.

Thymoma and paraganglioma are known causes of mediastinal masses, the latter being extremely rare. Thymomas arise from remnant thymic tissue in the anterior mediastinum; whereas, thoracic paragangliomas arise from para-aortic or para-vertebral sympathetic chain ganglion (derivatives of embryonic neural crest) in the middle or posterior mediastinum. Thymoma. Discussion. In this the patient with myasthenia gravis, the lesion was an invasive thymoma, and this study was done for pre-surgical evaluation. 99mTc Tetrofosmin like 99mTc MIBI, localizes to tissues with a high number of mitochondria implying hypermetabolic/dividing cells.

Examinations included posteroanterior and lateral (n = 154) and shallow oblique (n = 126) chest radiography, linear tomography (n = 80), and chest CT (n = 96).

Clinical, radiologic, and pathologic findings were noted. RESULTS: The masses occurred in 15 male and 12 female patients (mean age, 26.7 years). All 27 tumors were in the anterior … Thymoma radiology discussion including radiology cases.

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