Role of Contrast Enhanced Computed Tomography in Evaluation of Mediastinal Lesions

50 cases with clinical or radiological suspicion of mediastinal lesions were underwent CECT chest for characterization of mediastinal mass lesion and subsequently imaging findings were verified with pathological diagnosis. The most common compartment to be involved was antero-superior mediastinum (48 %) followed by middle (28 %) and posterior mediastinum (24 %). Predominant lesions were benign. The commonest lesion was tubercular lymphadenopathy (16 %). Thymic masses and metastatic lymphadenopathy (41 % total) were the most common mediastinal lesions in the anterior mediastinal compartment. Neural tumors (28.59 %) and metastatic lymphadenopathy (33.33 %) were the common lesions in middle and posterior mediastinal compartments respectively. Ascending aortic dissection was the predominant vascular lesion (8.3 %).
