Presentation1.pptx radiological imaging of mediastinal masses .

  1. 1. Radiological imaging of mediastinal masses. Dr/ ABD ALLAH NAZEER. MD.
  2. 2. Common mediastinal lesions.
  3. 3. Anterior mediastinal masses(50%). The anterior mediastinal masses usually displaced the anterior junctional line, obliterate the cardiophrenic angle and the retro-sternal space with hilum overlay sign. 1- Retro-sternal goiter. 2- Tortuous innominate artery. 3- Fat deposition. 4- Enlarged lymph nodes. 5- Ascending aortic aneurysm. 6- Thymoma. 7- Germ cell tumour. 8- Pleuro-pericardial cyst. 9- Morgagni hernia. 10- Para-thyroid adenoma.
  4. 4. Anterior mediastinal Lymphoma.
  5. 5. Morgagni hernia.
  6. 6. Thymic carcinoma.
  7. 7. Neck computed tomography shows rightward tracheal deviation (wide arrow) and tortuous innominate artery (narrow arrow) contact with trachea at right supra-clavicular area beneath subcutaneous layer (A), and at thoracic inlet level (B).
  8. 8. Enhancing 1.3-cm nodule in the right tracheoesophageal groove, with modest contrast washout representing a right inferior parathyroid gland in an orthotopic location. Pathology demonstrated a 3-g parathyroid adenoma.
  9. 9. Middle mediastinal masses(25%). The middle mediastinal masses widened the para-tracheal stripes, displaced the azygo-oesophageal recess on right side. 1- Lymph nodes enlargement. 2- Aortic arch aneurysm. 3- Enlarged pulmonary artery. 4- Dilated superior vena cava. 5- Bronchogenic cyst. 6- Tracheal lesions. 7- Cardiac tumours.
  10. 10. Bronchogenic cyst.
  11. 11. Aneurismal dilatation of the main pulmonary artery and the right pulmonary artery with peripheral pruning due to PH
  12. 12. Posterior mediastinal masses(25%). 1- Neurogenic tumours. 2- Pharyngio-esophygeal pouch. 3- Descending thoracic aortic aneurysm. 4- Hiatus hernia. 5- Esophageal lesions. 6- Para-vertebral masses. 7- Neuroenteric cysts. 8- Bochdalek hernia. 9- Pancreatic pseudocyst. 10- Abscess. 11- Fibrosis. 12- Extra-medullary hematopoiesis. 13- Lateral meningocele.
  13. 13. Posterior mediastinal schwannoma.
  14. 14. Schwannoma.
  15. 15. Esophageal lipoma and its fibrovascular stalk.
  16. 16. Bochdalek's hernia.
  17. 17. Descending thoracic aortic aneurysm.
  18. 18. Posterior mediastinal mass with para-vertebral abscess.
  19. 19. Neuroenteric cyst.
  20. 20. Lateral meningocele.
  21. 21. Thank You.
