Background
Large mediastinal masses are rare, and encompass a wide variety of diseases. Regardless of the diagnosis, all large mediastinal masses may cause compression or invasion of vital structures, resulting in respiratory insufficiency or hemodynamic decompensation. Detailed preoperative preparation is a prerequisite for favorable surgical outcomes and should include preoperative multimodality imaging, with emphasis on vascular anatomy and invasive characteristics of the tumor. A multidisciplinary team should decide whether neoadjuvant therapy can be beneficial. Furthermore, the anesthesiologist has to evaluate the risk of intraoperative mediastinal mass syndrome (MMS). With adequate preoperative team planning, a safe anesthesiological and surgical strategy can be accomplished.
Various surgical approaches are available to access the mediastinal and thoracic cavity. In the surgical management of large mediastinal tumors, a midline approach through a sternotomy, or a lateral approach through a thoracotomy are most often utilized.
Case Presentation
A 45-year aged woman, euglycemic and normotensive, had complaints of dyspnea for the past 3 months. She had a history of prior admissions to Thanjavur Medical College and Rohini hospital for the same. She was admitted to Kauvery Hospital where she underwent thorough investigations.
Past History
There is no significant past history like TB, Asthma, HTN, and DM.

CT – Thorax Report
Impression
Well defined rounded mixed solid cystic calcified lesion was noted in the left half of superior and anterior mediastinum, partially extending into the medial mediastinum with following features:
- Superiorly: It is reaching upto the level of left lung apex.
- Supero-Laterally: It reaches upto the left anterior pleural surface without infiltration.
- Supero-Medially: Mass effect on the Mediastinal structures and pulmonary artery without infiltration, mass effect on the left main bronchus without obstruction, it measures 128 × 102 × 84 mm. Mass effect noted in trachea which is shifted on the right side.
ECHO Report
