Aim: The aim of the study was to assess the sensitivity and specificity of computed tomography in the assessment of mediastinal masses. Helical CT with I / V contrast was performed in all patients. Place and Duration: In the Radiology Department of Jinnah Hospital Lahore for one-year duration from March 2019 to March 2020. Methods: Out of 100 patients, 31 had metastases with sensitivity and specificity 67.0% and 84.0%, 24 patients had tuberculosis with sensitivity and specificity 66.0% and 86.0%, 19 patients had lymphoma with sensitivity and specificity 47.0% and 90.0%, respectively. 26 patients had other weights. Overall sensitivity and specificity were 60.0% and 86.0%, respectively. Conclusion: It has been found that while CT is generally unable to distinguish between the different etiologies of mediastinal tumors, it cannot only support the diagnosis but can often lead to a specific diagnosis by some debilitating factors such as water, fat and calcium. It is therefore the examination of choice after a chest x-ray. Key words: Helical CT, mediastinal masses, histopathology.
