What is a mediastinal lesion?

A mediastinal lesion is an abnormal growth or mass located in the mediastinum, the central compartment of the thoracic cavity between the lungs. These lesions can be benign or malignant and may arise from various tissues, including lymphatic, thymic, or pulmonary. Symptoms often depend on the size and nature of the lesion and may include chest pain, cough, or respiratory difficulties. Diagnosis typically involves imaging studies and, in some cases, biopsy to determine the nature of the lesion.
