Presentation1.pptx, radiological imaging of adult neck masses.

  1. 1. Radiological imaging of adult neck masses. Dr/ ABD ALLAH NAZEER. MD.
  2. 2. Anatomy
  3. 3. Anatomical Considerations Prominent Landmarks Triangles of the Neck Regional Anatomy Lymph Node Levels Carotid Bulb Transverse Process of C1
  4. 4. Historical Points. Age: Up to 15yrs (pediatrics)  more than 90% benign 16 to 40 (young adult) More than 40yrs (older adults)  80% neoplasm  80% of them malignant (secondary>>primary) Time course immunodeficiency Prior trauma Travel, Irradiation, Surgery Associated symptoms  fever, dysphagia, weight loss, otalgia, hearing loss, respiratory difficulties Perform a FULL head and neck examination
  5. 5. Neck Masses: Epidemiology Adult neck masses are 90% malignant Pediatric neck masses are rarely malignant. Most common neck mass in children is an enlarged reactive lymph node 2ry to bacterial/viral infections Almost 50% of all 2 Y/O children have palpable normal cervical lymph nodes
  6. 6. Identification of Neck Masses On Basis Of Their Location Anterior Neck Swellings Lateral Neck Swellings Posterior Neck Swellings Diffuse Neck Swellings Identification of Neck Masses On Basis of their location:
  7. 7. Submental (Inframyelohyoid) dermoid.
  8. 8. Lipoma.
  9. 9. Submental lipoma
  10. 10. Thyroglossal duct cyst TGDC.
  11. 11. Submental metastatic lymph nodes with rim enhancement.
  12. 12. Midline Thyrohyoid Region Supraglottic Carcinoma.
  13. 13. Midline Thyrohyoid Region Metastatic PTC
  14. 14. Chondrosarcoma of the Hyoid. Bone.
  15. 15. Midline (Pre-laryngeal/Laryngeal) Thyroid (Pyramidal Lobe PTC).
  16. 16. Midline (Suprasternal & Pretracheal) Jugular Vein Phlebectasia.
  17. 17. PTC metastasis in a Para-tracheal L.N.
  18. 18. Anterior Paramedian Region, laryngeal tumour.
  19. 19. Submandibular Sialadenitis.
  20. 20. Granulomatous Lymphadenitis(Sarcoidosis).
  21. 21. Lymphoma
  22. 22. Submandibular Lipoma.
  23. 23. Plunging Ranula. CECT (A) shows a low density lesion in the sublingual space (arrow) that extends posterior medial to the SMG(B).
  24. 24. Phlepoectasia (Common facial V)
  25. 25. T.B. Parotitis & Lymphadenitis
  26. 26. Atypical Mycobacterial Cervical Lymphadenitis.
  27. 27. 2nd Arch Branchial Cleft Cysts
  28. 28. Branchial Cyst
  29. 29. Metastatic Lymph Nodes at carotid triangle.
  30. 30. B-Cell Lymphoma at carotid triangle.
  31. 31. Sympathetic Schwannoma Neurofibroma
  32. 32. Laryngomucocele
  33. 33. Posterior triangle L.N. enlargement may be due to; TB.
  34. 34. Supraclavicular lymph nodes..
