Gambaran dan Stadium Timoma pada CT-Scan
Thymoma is epithelial neoplasm arising from thymus gland commonly in anterior mediastinum. The incidence increases along with age at 40-50 year and reportedly 1-5 cases/milion/year. Masaoka system divides thymoma into 4 stadium. Stadium 1 is capsulated tumor, stadium
2 is invasion in fat tissue or mediastinal pleura, stadium 3 is invasion of surrounding organs, pericardium, great vessel and lung, stadium 4a is tumor spreading to pleura or pericardium, and stadium 4a is hematogenous or lymphatic metastases. Imaging has great role in diagnosis
and thymoma staging. CT is the imaging modality of choice to evaluate thymoma and to differentiate it from other anterior mediastinum abnormalities which correlated with therapy and prognosis from thymoma.
