Abstract: The article provides a case report of the patient with mediastinitis. This case report shows the importance of multispiral computed tomography in the diagnostics of tumors of this localization, demonstrates the need of proper preparation of patient for examination and use of CT with intravenous contrast enhancement, multiplanar reconstruction images to obtain information about the nature of blood flow, determining the structure of esophagus walls and the ratio of detected changes with surrounding organs and vascular structures, which is particularly important for treatment planning.
